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 byte controlled. The flip-flops appear 5.4 ns t max (V 3.3V), 20 PA I max PD CC CC transparent to the data when the Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup time Power down high impedance inputs and outputs is latched. Data appears on the bus when the Output Supports live insertion/withdrawal (Note 1) Enable (OE) is LOW. When OE is HIGH, the outputs are in r24 mA output drive (V 3.0V) CC a high impedance state. Uses proprietary noise/EMI reduction circuitry The LCX16373 is designed for low voltage (2.5V or 3.3V) Latch-up performance exceeds 500 mA V applications with capability of interfacing to a 5V signal CC environment. ESD performance: The LCX16373 is fabricated with an advanced CMOS tech- Human body model 2000V nology to achieve high speed operation while maintaining Machine model 200V CMOS low power dissipation. 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.
