FACT DATA
The MC74AC620/74ACT620 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
