54F/74F545 Octal Bidirectional

Transceiver with TRI-STATE Outputs

General Description

Features

Higher drive than 8304

The ’F545 is an 8-bit, TRI-STATE, high-speed transceiver. It

provides bidirectional drive for bus-oriented microprocessor

and digital communications systems. Straight through bidi-

rectional transceivers are featured, with 24 mA (20 mA Mil)

bus drive capability on the A ports and 64 mA (48 mA Mil)

bus drive capability on the B ports.

8-bit bidirectional data flow reduces system package

count

TRI-STATE inputs/outputs for interfacing with bus-ori-

ented systems

24 mA (20 mA Mil) and 64 mA (48 mA Mil) bus drive

capability on A and B ports, respectively

Transmit/Receive and Output Enable simplify control

logic

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

of logic signals through the bidirectional transceiver. Trans-

mit enables data from A ports to B ports; Receive enables

data from B ports to A ports. The Output Enable input dis-

ables both A and B ports by placing them in a TRI-STATE

condition.

Guaranteed 4000V minimum ESD protection
