1 / 6 page © 2002 Fairchild Semiconductor Corporation DS500632 www.fairchildsemi.com September 2001 Revised February 2002 74ALVCH162244 Low Voltage 16-Bit Buffer/Line Driver with Bushold and 26 Ω Series Resistor in Outputs General Description The ALVCH162244 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 ALVCH162244 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 74ALVCH162244 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 74ALVCH162244 is designed for low voltage (1.65V to 3.6V) VCC applications with output capability up to 3.6V. The 74ALVCH162244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation. Features s 1.65V to 3.6V VCC supply operation s 3.6V tolerant control inputs and outputs s Bushold on data inputs eliminates the need for external pull-up/pull-down resistors s 26 Ω series resistors in outputs s tPD 4.2 ns max for 3.0V to 3.6V VCC 4.9 ns max for 2.3V to 2.7V VCC 7.6 ns max for 1.65V to 1.95V VCC s Uses patented noise/EMI reduction circuitry s Latch-up conforms to JEDEC JED78 s ESD performance: Human body model > 2000V Machine model > 200V Ordering Code: Devices also available in Tape and Reel.
