Description

These bus transceivers are designed for a synchronous three-way communication between four-line data buses. They

give the designer a choice of selecting inverting, noninverting or a combination of inverting and noninverting data paths

with 3-state outputs.

data are to be transferred. The port for any bus selected for input and any other bus not enabled for output will be at

high impedance.

Features

• High Speed Operation

• High Output Current: Fanout of 15 LSTTL Loads

• Wide Operating Voltage: V

• Low Input Current: 1 µA max

• Low Quiescent Supply Current: I

• Ordering Information
