Electronic components AD548 PRODUCT DESCRIPTION and IC trading market Site recommended

PRODUCT DESCRIPTION follows:
The electronic component AD548 is a low power, precision monolithic operational amplifier. It offers both low  bias current (10 pA max, warmed up) and low quiescent current (200 μA max) and is  fabricated with ion-implanted FET and laser wafer trimming technologies.

Input bias current is guaranteed over the AD548’s entire common-mode voltage range.
The economical J grade has a maximum guaranteed input offset voltage of less than 2 mV and  an input offset voltage drift of less than 20 μV/°C. This level of dc precision is  achieved utilizing Analog’s laser wafer drift trimming process. The combination of low quiescent current and low offset voltage drift minimizes changes in input offset  voltage due to self-heating effects.

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 (VCCcable) 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 VCCcable supply to provide  proper termination and pull-ups for open drain mode.

DESCRIPTION about electronic component LVX273 and Industry web recommended

The semiconductor  LVX273 has eight edge-triggered D-type flip-flops with
individual D inputs and Qoutputs. The common buffered Clock (CP) and Master Reset (MR)
input load and reset (clear) all flip-flops simultaneously.
The register is fully edge-triggered. The state of each Dinput, one setup time before the
LOW-to-HIGH clock transition,is transferred to the corresponding flip-flop’s Q output.
All outputs will be forced LOW independently of Clock or Data inputs by a LOW voltage
level on the MR input.
The device is useful for applications where the true output only
is required and the Clock and Master Reset are common to all storage elements. The inputs
tolerate up to 7V allowing interface of 5V systems to 3V systems.

Ic components Industry recommended and DESCRIPTION about model

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.

on the same chip.

By using mixed technology it has been possible to optimize the logic circuitry and the
power stage to achieve the best possible performance. The DMOS output transistors can
operate at supply voltages up to 42V and efficiently at high switching speeds. All the
logic inputs are TTL, CMOS and mC compatible. Each channel (half-bridge) of the device is
controlled by a separate logic input, while a common enable controls both channels.
The I.C. is mounted in three different packages.
