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.

■ ICC and IOZ reduced by 50%
■ Noninverting buffers
■ Bidirectional data path
■ A and B outputs source/sink 24 mA
■ ’ACT245 has TTL-compatible inputs
■ Standard Microcircuit Drawing (SMD)
