Octal Bidirectional Transceiver with 3-STATE Outputs

General Description

Features

The 74F545 is an 8-bit, 3-STATE, high-speed transceiver. It

provides bidirectional drive for bus-oriented microproces-

sor and digital communications systems. Straight through

bidirectional transceivers are featured, with 24 mA bus

drive capability on the A Ports and 64 mA bus drive capa-

bility on the B Ports.

■ Higher drive than 8304

■ 8-bit bidirectional data flow reduces system package

count

■ 3-STATE inputs/outputs for interfacing with bus-oriented

systems

■ 24 mA and 64 mA bus drive capability on A and B Ports,

respectively

One input, Transmit/Receive (T/R) determines the direction

of logic signals through the bidirectional transceiver. Trans-

mit enables data from A-to-B Ports; Receive enables data

from B-to-A Ports. The Output Enable input disables both A

and B Ports by placing them in a 3-STATE condition.

■ Transmit/Receive and Output Enable simplify control

logic

■ Guaranteed 4000V minimum ESD protection
