Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com 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.

The Transmit/ Receive (T/R ) input determines the direction 3 V Data Flow at A-Port and 5 V Data Flow at B- of data flow. Transmit (active-HIGH) enables data from Port A-ports to B-ports receive (active-LOW) enables data Outputs Source / Sink: 24 mA from B-ports to A-ports. The output enable input, when HIGH, disables both A- and B-ports by placing them in a Guaranteed Simultaneous Switching Noise Level high-impedance condition. The A-port interfaces with and Dynamic Threshold Performance the 3 V bus the B-port interfaces with the 5 V bus. Implements Proprietary EMI Reduction Circuitry The 74LVX3245 is suitable for mixed-voltage Functionally Compatible with the 74 Series 245 applications, such as notebook computers using 3.3 V CPU and 5V peripheral components.
