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 nibble controlled. Each nibble has separate 3-STATE control inputs which can be shorted together for full 16-bit operation. The LCXH162244 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. ■ 5V tolerant control inputs and outputs In addition, the outputs include equivalent 26: (nominal) series resistors to reduce overshoot and undershoot and are designed to sink/source up to 12 mA at VCC 3.0V. ■ Power down high impedance inputs and outputs The LCXH162244 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCXH162244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. ■ Latch-up performance exceeds 500 mA ■ 2.3V–3.6V VCC specifications provided ■ Outputs include equivalent series resistance of 26: to make external termination resistors unnecessary and reduce overshoot and undershoot ■ Bushold on data inputs eliminates the need for external pull-up/pull-down resistors ■ 5.3 ns tPD max (VCC 3.0V), 20 PA ICC max ■ r12 mA output drive (VCC 3.0V) ■ Implements proprietary noise/EMI reduction circuitry ■ ESD performance: Human body model ! 2000V Machine model ! 200V Ordering Code: Order Number Package Number 74LCXH162244MEA MS48A 48-Lead Small Shrink Outline Package (SSOP), JEDEC MO-118, 0.300" Wide [RAIL] Package Description 74LCXH162244MEX MS48A 48-Lead Small Shrink Outline Package (SSOP), JEDEC MO-118, 0.300" Wide [TAPE and REEL] 74LCXH162244MTD MTD48 48-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide [RAIL] 74LCXH162244MTX MTD48 48-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide [TAPE and REEL] © 2005 Fairchild Semiconductor Corporation DS500249 www.fairchildsemi.com 74LCXH162244 Low Voltage 16-Bit Buffer/Line Driver with Bushold and 26: Series Resistors in Outputs September 2000 Revised May 2005 74LCXH162244 Connection Diagram Logic Symbol Pin Descriptions Pin Names www.fairchildsemi.com 2 Description OEn Output Enable Input (Active LOW) I0–I15 Bushold Inputs O0–O15 Outputs Inputs Outputs I0–I3 OE1 Inputs O0–O3 OE3 Outputs I8–I11 O8–O11 L L L L L L L H H L H H H X Z H X Z Inputs OE2 Outputs I4–I7 Inputs O4–O7 OE4 Outputs I12–I15 O12–O15 L L L L L L L H H L H H H X Z H X Z H HIGH Voltage Level L LOW Voltage Level X Z Immaterial High Impedance Functional Description identically, but independent of the other. The control pins can be shorted together to obtain full 16-bit operation. The 3-STATE outputs are controlled by an Output Enable (OEn) input for each nibble. When OEn is LOW, the outputs are in 2-state mode. When OEn is HIGH, the outputs are in the high impedance mode, but this does not interfere with entering new data into the inputs. The LCXH162244 contains sixteen non-inverting buffers with 3-STATE standard outputs. The LCXH162244 data inputs include active bushold circuitry eliminating the need for pull-up resistors to hold unused or floating data inputs at a valid logic level. The devise is also designed with 26: series resistors in the outputs. This design reduces line noise in applications such as memory address drivers, clock drivers and bus transceiver/transmitters.
