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 determines
the direction of data flow through the bidirectional trans-
ceiver. 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.
