Bus Transceiver with LSTTL
Compatible Inputs
High−Performance Silicon−Gate CMOS
device may be used as a level converter for interfacing TTL or NMOS
outputs to High Speed CMOS inputs.
used for 2−way asynchronous 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.
Features
*Equivalent to a two−input NAND gate.
