74LVQ245_01 Overview

Low Voltage Octal Bidirectional Transceiver

74LVQ245 Low Voltage Octal Bidirectional Transceiver with 3-STATE Outputs
February 1992
Revised June 2001
74LVQ245
Low Voltage Octal Bidirectional Transceiver
with 3-STATE Outputs
General Description
The LVQ245 contains eight non-inverting bidirectional buff-
ers with 3-STATE outputs and is intended for bus-oriented
applications. Current sinking capability is 12 mA at 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.
