Octal 3-State Inverting Transciever
MC74ACT640
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
