1 / 7 page © 2000 Fairchild Semiconductor Corporation DS500231 www.fairchildsemi.com January 2000 Revised March 2000 74VCXH162244 Low Voltage 16-Bit Buffer/Line Driver with Bushold and 26 Ω Series Resistor in Outputs General Description The VCXH162244 contains sixteen non-inverting buffers with 3-STATE outputs to be employed as a memory and address driver, clock driver, or bus oriented transmitter/ receiver. The device is nibble (4-bit) controlled. Each nibble has separate 3-STATE control inputs which can be shorted together for full 16-bit operation. . The VCXH162244 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 The 74VCXH162244 is also designed with 26 Ω series resistors in the outputs. This design reduces line noise in applications such as memory address drivers, clock driv- ers, and bus transceivers/transmitters. The 74VCXH162244 is designed for low voltage (1.65V to 3.6V) VCC applications with output capability up to 3.6V. The 74VCXH162244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintain- ing low CMOS power dissipation.
