74AC245 • 74ACT245
Octal Bidirectional Transceiver with 3-STATE
Inputs/Outputs
General Description
The AC/ACT245 contains eight non-inverting bidirectional
buffers with 3-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.
