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 designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The device is byte controlled. Each byte has separate control inputs which could 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 LCXH16245 data inputs include active bushold circuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level. ■ 2.3V–3.6V VCC specifications provided The LCXH16245 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. ■ 4.5 ns tPD max (VCC 3.3V), 20 PA ICC max ■ Power-down high impedance outputs ■ Bushold on inputs eliminates the need for external pull-up/pull-down resistors ■ r24 mA output drive (VCC 3.0V) ■ Implements patented noise/EMI reduction circuitry ■ Latch-up performance conforms to the requirements of JESD78 ■ ESD performance: Human body model ! 2000V Machine model ! 200V ■ Also packaged in plastic Fine-Pitch Ball Grid Array (FBGA) Ordering Code: Order Number Package Number Package Description 74LCXH16245G (Note 1) (Note 2) BGA54A 54-Ball Fine-Pitch Ball Grid Array (FBGA), JEDEC MO-205, 5.5mm Wide 74LCXH16245MTD (Note 2) MTD48 48-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide Note 1: Ordering Code “G” indicates Trays.
