74AC245, 74ACT245
Octal Bidirectional Transceiver with 3-STATE
Inputs/Outputs
Features
ICC and IOZ reduced by 50%
Non-inverting buffers
Bidirectional data path
A and B outputs source/sink 24mA
ACT245 has TTL-compatible inputs
General Description
The AC/ACT245 contains eight non-inverting bidirec-
tional buffers with 3-STATE outputs and is intended for
bus-oriented applications. Current sinking capability is
24mA at 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 placing them in a HIGH Z condition.
