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 device is designed for low voltage 4.5 ns t max (V 3.3V), 20 PA I max PD CC CC (2.5V or 3.3V) V applications with capability of interfac- CC Power down high impedance inputs and outputs ing to a 5V signal environment. The device is byte con- trolled. Each byte has separate control inputs which could Supports live insertion/withdrawal (Note 1) be shorted together for full 16-bit operation. The T/R inputs r24 mA output drive (V 3.0V) CC determine the direction of data flow through the device. Uses patented noise/EMI reduction circuitry The OE inputs disable both the A and B ports by placing them in a high impedance state. Latch-up performance exceeds 500 mA The LCX16245 is fabricated with an advanced CMOS tech- ESD performance: nology to achieve high speed operation while maintaining Human body model 2000V CMOS low power dissipation. 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 down, OE should be tied to V through a pull-up resistor: the minimum value or the CC resistor is determined by the current-sourcing capability of the driver.
