MC74ACT640
Octal 3-State Inverting
Transciever
The MC74ACT640 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.
Features
• Bidirectional Data Path
• A and B Outputs Sink 24 mA/Source −24 mA
• TTL Compatible Inputs
• These are Pb−Free Devices
