54AC 74AC245 54ACT 74ACT245

Octal Bidirectional Transceiver

with TRI-STATE Inputs Outputs

General Description

The ’AC ’ACT245 contains eight non-inverting bidirectional

buffers with TRI-STATE outputs and is intended for bus-ori-

ented applications Current sinking capability is 24 mA at

both the A and B ports The Transmit Receive (T R) input

determines the direction of data flow through the bidirec-

tional 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 placing them in a

HIGH Z condition
