Octal 3-State Inverting
Bus Transceiver
High–Performance Silicon–Gate CMOS
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
communication between data buses. The device has an active–low Output
Enable pin, which is used to place the I/O ports into high–impedance states.
The Direction control determines whether data flows from A to B or from B
to A.
