54AC245 54ACT245
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-oriented 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 bidi-
rectional 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.
