74ABT245 Octal Bi-Directional Transceiver with 3-STATE Outputs
September 1991
Revised November 1999
74ABT245
Octal Bi-Directional Transceiver with 3-STATE Outputs
General Description
The ABT245 contains eight non-inverting bidirectional buff-
ers 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 deter-
mines 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.
