Octal Bidirectional Transceiver with TRI-STATE®
Inputs/Outputs
General DescriptionThe ’AC/’ACT245 contains eight non-inverting bidirectional
buffers with TRI-STATE outputs andis intendedfor
bus-oriented applications. Current sinking capabilityismAat both theAandB ports. TheTransmit/Receive (T/R)
input determinesthe directionof dataflow throughthe bidi-
rectional transceiver. Transmit (active-HIGH) enables data
fromA portstoB ports; Receive (active-LOW) enables data
fromB portstoA ports. The Output Enable input, when
HIGH,disables both AandB ports byplacing themina HIGH condition.
