74F545

Octal Bidirectional Transceiver with 3-STATE Inputs/Outputs

Generic P/N F545

Data Sheet

General Description

The 'F545 is an 8-bit, 3-STATE, high-speed transceiver. It provides bidirectional drive for bus-oriented microprocessor and digital communications systems. Straight through bidirectional 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.

One input, Transmit/Receive (T/R#) determines the direction of logic signals through the bidirectional transceiver. Transmit enables data from A ports to B ports; Receive enables data from B ports to A ports. The Output Enable input disables both A and B ports by placing them in a 3-STATE condition.

Features

• 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 (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
• Guaranteed 4000V minimum ESD protection
• Pin for Pin compatible with Intel 8286
