OCTAL BIDIRECTIONAL

TRANSCEIVER WITH

3-STATE OUTPUTS

The MC74AC643/74ACT643 octal bus transceiver is designed for asynchronous

two-way communication between data buses. The device transmits data from bus A

to bus B when T/R = HIGH, or from bus B to bus A when T/R = LOW. The enable

input can be used to disable the device so the buses are effectively isolated.

• Bidirectional Data Path

• A and B Outputs Sink 24 mA/Source –24 mA

• ′ACT643 Has TTL Compatible Inputs
