General Description
The ’AC/’ACT245 contains eight non-inverting bidirectional
bufferswith TRI-STATE outputsandis intendedfor bus-ori-
ented applications. Current sinking capabilityis24mAat
boththeAandB ports. The Transmit/Receive (T/R) input
determinesthe directionof data flow throughthe bidirec-
tional transceiver. Transmit (active-HIGH) enables data
fromA portstoB ports; Receive (active-LOW) enables data
fromB portstoA ports. The Output Enable input, when
HIGH, disables bothA andB portsby placing themina
HIGHZ condition.
