Description Introduction about IC parts 74LVX161284A
The electronic components LVX161284A contains eight bidirectional data buffers and eleven control/status buffers to implement a full IEEE 1284 compliant interface. The device supports the IEEE 1284 standard, with the exception of output slew rate,and is intended to be used in an Extended Capabilities Port mode (ECP). The pinout allows for easy semiconductor connection from the Peripheral (A-side) to the Host (cable side).
Outputs on the cable side can be configured to be either open drain or high drive (± 14 mA) and are connected to aseparate power supply pin (VCCcable) to allow these outputs
to be driven by a higher supply voltage than the A-side. The pull-up and pull-down series termination resistance of these outputs on the cable side is optimized to
drive an external cable. In addition, all inputs (except HLH) and outputs on the cable side contain internal pull-up resistors connected to the VCCcable supply to provide proper termination and pull-ups for open drain mode.

Electronic component famous enterprise is Hqew.net,many hot model such as Lm358,lm317,ne555 ,lm324,lm339and so on,other 74LV74,Introduces the FEATURES about electronic components 74LV74 and electronic component lm358 details.
The 74LV74 is a low-voltage Si-gate CMOS device and is pin and
function compatible with 74HC/HCT74.
The 74LV74 is a dual positive edge triggered, D-type flip-flop with
individual data (D) inputs, clock (CP) inputs, set (SD) and (RD)
inputs; also complementary Q and Q outputs.
The set and reset are asynchronous active LOW inputs and operate
independently of the clock input. Information on the data input is
transferred to the Q output on the LOW-to-HIGH transition of the
clock pulse. The D inputs must be stable one set-up time prior to the
LOW-to-HIGH clock transition, for predictable operation.
Schmitt-trigger action in the clock input makes the circuit highly
tolerant to slower clock rise and fall times.
The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages.

Description and Applications about electronic component DG408
The electronic components DG408 and DG409 feature lower signal ON resistance (<100Ω) and faster switch transition time (tTRANS < 250ns) compared to the DG508A or DG509A. Charge injection has
been reduced, simplifying sample and hold applications. The improvements in the DG408
series are made possible by using a high-voltage silicon-gate process. An epitaxial layer
prevents the latch-up associated with older CMOS technologies. Power supplies may be
single-ended from +5V to +34V, or split from ±5V to ±20V.
The analog switches are bilateral, equally matched for AC or bidirectional signals. The ON
resistance variation withanalog signals is quite low over a ±5V analog input range.

Ic components DG408 and DG409 description introduction
The electronic components DG408 and electronic component DG409 feature lower signal ON resistance (<100Ω) and faster switch transition time (tTRANS < 250ns) compared to the DG508A or DG509A. Charge injection has been reduced, simplifying sample and hold applications.
The improvements in the DG408 series are made possible by using a high-voltage silicon-gate process. An epitaxial layer prevents the latch-up associated with older CMOS
technologies. Power supplies may be single-ended from +5V to +34V, or split from ±5V to ±20V.
The analog switches are bilateral, equally matched for AC or bidirectional signals. The ON resistance variation with analog signals is quite low over a ±5V analog input range.

Description about Ic components VND5004A-E and VND5004ASP30-E Features
The electronic components VND5004ATR-E and electronic component VND5004ASP30-E are devices made using STMicroelectronics VIPower
technology. They are intended for driving resistive or inductive loads with one side connected to ground.
Active VCC pin voltage clamp and load dump protection circuit protect the devices against transients on the Vcc pin (see ic components ISO7637 transient compatibility table). These devices integrate an analog current sense which delivers a current proportional to the load current (according to a known ratio) when CS_DIS is driven low or left open. When CS_DIS is driven high, the CURRENT SENSE pin is high impedance.
Output current limitation protects the devices in overload condition. In case of long duration overload, the devicesa limit the dissipated power to a safe level up to thermal shut-down intervention. Thermal shut-down with automatic restart allows the device to recover normal operation as soon as a fault condition disappears.

Many features of Ic components LM101A/LM201A/LM301A
This Series of electronic components offers many features which make its application nearly foolproof:
overload protection on the input and output, no latch-up when the common mode range is
exceeded, and freedom from oscillations and compensation with a single 30 pF capacitor. It has advantages over internally compensated amplifiers in that the frequency
compensation can be tailored to the particular application.
For example, in low frequency circuits it can be overcompensated for increased stability margin. Or the compensation can be optimized to give more than a factor of
ten improvement in high frequency performance for most applications.

description information of electronic components lm358dr
These devices consist of two independent,high-gain, frequency-compensated operational
amplifiers designed to operate from a single supply over a wide range of voltages. Operation from split supplies also is possible if the difference between the two supplies is 3 V to 32 V (3 V to 26 V for the electronic components LM2904), and VCC is at least 1.5 V more positive than the input common-mode voltage. The low supply-current drain is independent of the magnitude of the supply voltage.
Applications include transducer amplifiers, dc amplification blocks, and all the conventional operational amplifier circuits that now can be implemented more easily in single-supply-voltage systems. For example, these devices can be operated directly from the standard 5-V supply used in digital systems and easily can provide the required interface ic components without additional ±5-V supplies.

IC parts LM2904,LM358/LM358A performance description
performance of many Ic parts models keywords is similar,such as LM2904,LM358/LM358A,
LM258/LM258A,here electronic components performance description:
frequency compensated operational amplifiers which were designed specifically to
operate from a single power supply over a wide range of voltage. Operation from split
power supplies is also possible and the low power supply current drain is independent
of the magnitude of the power supply voltage.
Application areas include transducer amplifier, DC gain blocks and all the conventional
OP-AMP circuits which now can be easily implemented in single power supply systems.

AN ALL-IN-ONE GUIDE TO ELECTRONIC COMPONENT SPECIFICATIONS AND APPLICATIONS
With this handy benchtop reference, you'll have at your fingertips a one-stop source of practical information on virtually every kind of electronic component. In electronic components: A COMPLETE REFERENCE FOR PROJECT BUILDERS, Delton T. Horn provides you with the important working characteristics, specifications, and uses for each component listed.
Who can tell me the question about electronic component
Hi hope someone could help me understand the workings of electronic components.
I think I am right in saying that all electronic components require energy for them to function.
If you connect a battery to the component to supply the energy then this is supplied from the electrochemical energy in the battery.
The battery pushes electrons up a potential difference through the circuit from - to +
Here I get a bit hazy
The electrons are pushed through the component and 'lose energy'? while they are travelling through it? This lost energy is used by the resistors, lcds etc to do 'their thing'.
What is different in the electron that leaves the neg terminal and reaches the pos terminal?
Is it in a lower energy state?
Also this electron that returns to the battery. Dosnt it go on to take part in a chemical REDOX reaction? How does that happen?
Why does it need to be in a lower energy state to work?
Sorry total confusion as you see. Id be grateful if someone could give me a heads up!
