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 Semiconductor’s 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 T/R input determines the direction of data flow. The OE input disables both the A and B ports by plac- ing them in a high impedance state. The 74VCX245 is designed for low voltage (1.4V to 3.6V) VCC applications with I/O compatibility up to 3.6V. The 74VCX245 is fabricated with an advanced CMOS technology to achieve high-speed operation while main- taining low CMOS power dissipation. Features ■1.4V to 3.6V VCC supply operation ■3.6V tolerant inputs and outputs ■Power-off high impedance inputs and outputs ■Supports Live Insertion and Withdrawal (Note 1) ■ tPD 3.5 ns max for 3.0V to 3.6V VCC ■Static Drive (IOH/IOL) r24 mA @ 3.0V VCC circuitry ■Latchup performance exceeds 300 mA ■ESD performance: Human body model ! 2000V Machine model ! 200V ■Leadless DQFN Pb-Free package Note 1: To ensure the high impedance state during power up and power down, OEn should be tied to VCC through a pull up resistor. The minimum value of the resistor is determined by the current sourcing capability of the driver. Ordering Code: Pb-Free package per JEDEC J-STD-020B. Note 2: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
