74LVX245
Low Voltage Octal Bidirectional Transceiver
General Description
The LVX245 contains eight non-inverting bidirectional buff-
ers and is intended for bus-oriented applications. 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 placing them in a high impedance condi-
tion.
Features
s Ideal for low power/low noise 3.3V applications
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
