Octal Bidirectional
Transceiver with 3State
Inputs/Outputs
The MC74AC245/74ACT245 contains eight non
inverting
bidirectional buffers with 3
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 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.
