74LCXH16244 Low Voltage 16-Bit Buffer/Line Driver with Bushold September 2000 Revised September 2000 74LCXH16244 Low Voltage 16-Bit Buffer/Line Driver with Bushold General Description The LCXH16244 contains sixteen non-inverting buffers with 3-STATE outputs designed to be employed as a memory and address driver, clock driver, or bus oriented transmitter/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 LCXH16244 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. The LCXH16244 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCXH16244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. Features s 5V tolerant control inputs and outputs s 2.3V- 3.6V VCC specifications provided s 4.5 ns t PD max (VCC = 3.0V), 20 µA ICC max s Bushold on inputs eliminates the need for external pull-up/pull-down resistors s Power down high impedance inputs and outputs s ±24 m A output drive (VCC = 3.0V) s Implements patented noise/EMI reduction circuitry s Latch-up performance exceeds 500 m A s ESD performance: Human body model > 2000V Machine model > 200V Ordering Code: Order Number 74LCXH16244MEA 74LCXH16244MTD Package Number MS48A MTD48 Package Description 48-Lead Small Shrink Outline Package (SSOP), JEDEC MO-118, 0.300 Wide 48-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 6.1mm Wide Devices also available in Tape and Reel.
