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 nibble controlled. Each nibble has separate 3-STATE control inputs which can be shorted Power down high impedance inputs and outputs together for full 16-bit operation. Supports live insertion/withdrawal (Note 1) The LCX16240 is designed for low voltage (2.5V or 3.3V) r24 mA output drive (V 3.0V) CC V applications with capacity of interfacing to a 5V signal CC Implements proprietary noise/EMI reduction circuitry environment. Latch-up performance exceeds 500 mA The LCX16240 is fabricated with an advanced CMOS tech- ESD performance: nology to achieve high speed operation while maintaining CMOS low power dissipation. Human body model 2000V Machine model 200V 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.
