The 74ABT544PW is a bus transceiver, consisting of a receiver and a driver, that is part of the 74ABT family of logic components. The 74ABT544PW is designed to have improved performance with higher speed and greater noise immunity in order to provide lower power dissipation and surface mount board design. It is used in many applications to allow for communication between input and output circuits.

Features

• Standard CMOS Input and Output Interface
• Low power dissipation
• Low voltage operation
• Latch-up protection exceeding 200 mA

Applications

• Computer buses
• Networks
• Multi-drop communications
• High speed buffers
• Multiplexers

Working Principle

The 74ABT544PW is a multiplier supply logic component, meaning it can work from a single 5V supply or dual split supplies. It acts as a buffer, receiving signals from input circuits and sending them to output circuits. The transceiver has two separate data paths for data to flow along, one for input and one for output. As such, it can detect logic low and logic high signals from an input and pass it on to other circuits. It is designed to operate with very low power dissipation, due to its CMOS technology.

Pin configuration

There are 20 pins in the 74ABT544PW, which are all numbered consecutively, starting with pin 1. Pin 1 is the GND (ground) pin and is used to provide a reference voltage for the component. Pin 2 is the IN (input) pin and is used to receive signals from input circuits. Pin 3 is the OUT (output) pin and is used to send signals to output circuits. Pin 4 is the EN (enable) pin and is used to enable or disable the component. Pins 5-8, 10-13, and 15-19 are the A and B data pins and are used to receive and send signals along the input and output data paths.

Conclusion

The 74ABT544PW is a bus transceiver, consisting of a receiver and a driver, which can provide accurate communication between input and output circuits. It works in many applications, including computer buses, networks, high speed buffers, and multiplexers. Its low voltage operation, low power dissipation, and latch-up protection make a reliable and efficient data transceiver. Its pin configuration consists of 20 pins, including an input, output and enable pin, and data pins for the A and B data paths.
