Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

74LVX245
Low Voltage Octal Bidirectional Transceiver
General Description Features
The LVX245 contains eight non-inverting bidirectional buff- Ideal for low power/low noise 3.3V applications
ers and is intended for bus-oriented applications. The
Guaranteed simultaneous switching noise level and
Transmit/Receive (T/R) input determines the direction of
dynamic threshold performance
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.
