1 / 9 page © 2005 Fairchild Semiconductor Corporation DS500249 www.fairchildsemi.com September 2000 Revised May 2005 74LCXH162244 Low Voltage 16-Bit Buffer/Line Driver with Bushold and 26 : Series Resistors in Outputs General Description The LCXH162244 contains sixteen non-inverting buffers with 3-STATE outputs designed to be employed as a mem- ory and address driver, clock driver, or bus oriented trans- mitter/receiver. 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 cir- cuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level. 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. 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 maintain- ing CMOS low power dissipation. Features s 5V tolerant control inputs and outputs s 2.3V–3.6V VCC specifications provided s Outputs include equivalent series resistance of 26 : to make external termination resistors unnecessary and reduce overshoot and undershoot s Bushold on data inputs eliminates the need for external pull-up/pull-down resistors s 5.3 ns tPD max (VCC 3.0V), 20 PA ICC max s Power down high impedance inputs and outputs s r12 mA output drive (VCC 3.0V) s Implements patented noise/EMI reduction circuitry s Latch-up performance exceeds 500 mA s ESD performance: Human body model ! 2000V Machine model ! 200V Ordering Code: Order Number Package Number Package Description 74LCXH162244MEA MS48A 48-Lead Small Shrink Outline Package (SSOP), JEDEC MO-118, 0.300" Wide [RAIL] 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] |
