74ABT245

Octal Bi-Directional Transceiver with 3-STATE Outputs

Features

General Description

■ Bidirectional non-inverting buffers

The ABT245 contains eight non-inverting bidirectional

buffers with 3-STATE outputs and is intended for bus-

oriented applications. Current sinking capability is 64 mA

on both the A and B ports. The Transmit/Receive (T/R)

input determines the direction of data flow through the

bidirectional transceiver. Transmit (active HIGH) enables

data from A Ports to B Ports; Receive (active LOW)

enables data from B Ports to A Ports. The Output Enable

input, when HIGH, disables both A and B ports by plac-

ing them in a HIGH Z condition.

■ A and B output sink capability of 64mA, source

capability of 32mA

■ Guaranteed output skew

■ Guaranteed multiple output switching specifications

■ Output switching specified for both 50pF and 250pF

loads

■ Guaranteed simultaneous switching, noise level and

dynamic threshold performance

■ Guaranteed latchup protection

■ High-impedance, glitch-free bus loading during entire

power up and power down cycle

■ Nondestructive, hot-insertion capability

■ Disable time is less than enable time to avoid bus

contention
