54FCT573

Octal D-Type Latch with TRI-STATE^®Outputs

General Description

The ’FCT573 is an octal latch with buffered common Latch

Enable (LE) and buffered common Output Enable (OE) in-

puts.

Features

n Inputs and outputs on opposite sides of package allow

easy interface with microprocessors

n Useful as input or output port for microprocessors

n TTL input and output level compatible

n CMOS power consumption

This device is functionally identical to the ’FCT373 but has

different pinouts.

n Functionally identical to ’FCT373

n TRI-STATE outputs for bus interfacing

n Output sink capability of 32 mA, source capability of

12 mA

n Standard Microcircuit Drawing (SMD) 5962-8863901
