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 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 device is byte controlled. Each byte has separate 3-STATE control inputs which can be shorted together for full 16-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs disable both the A and B ports by placing them in a high impedance state. The 74ALVC16245 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O compatibility up to 3.6V. ■ 1.65V–3.6V VCC supply operation The 74ALVC16245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation. ■ Uses patented noise/EMI reduction circuitry ■ 3.6V tolerant inputs and outputs ■ tPD 3.0 ns max for 3.0V to 3.6V VCC 3.5 ns max for 2.3V to 2.7V VCC 6.0 ns max for 1.65V to 1.95V VCC ■ Power-down high impedance inputs and outputs ■ Supports live insertion/withdrawal (Note 1) ■ Latchup conforms to JEDEC JED78 ■ ESD performance: Human body model ! 2000V Machine model !200V ■ Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA) Note 1: To ensure the high-impedance state during power up or power down, OE 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.
