74LVX245
Low Voltage Octal Bidirectional Transceiver
General Description
The LVX245 contains eight non-inverting bidirectional buff-
ers 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 (ac-
tive-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
Features
Y _{Ideal for low power low noise 3 3V applications}
Y _{Available in SOIC JEDEC SOIC EIAJ and TSSOP}
packages
Y _{Guaranteed simultaneous switching noise level and}
dynamic threshold performance
