Octal 3-STATE Bus Transceiver

General Description

This advanced low power Schottky device contains 8 pairs

of 3-STATE logic elements configured as octal bus trans-

ceivers. These circuits are designed for use in memory,

microprocessor systems and in asynchronous bidirectional

data buses. Two way communication between buses is

controlled by the (DIR) input. Data transmits either from the

A bus to the B bus or from the B bus to the A bus. Both the

driver and receiver outputs can be disabled via the (G)

enable input which causes outputs to enter the high imped-

ance mode so that the buses are effectively isolated.

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
