General Description
The ABT245 contains eight non-inverting bidirectional
buffers with 3-STATE outputs and is intended for bus-
oriented applications. Current sinking capability is 64 mA
on 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 plac-
ing them in a HIGH Z condition.
