74ALVCH162244 Low Voltage 16-Bit Buffer/Line Driver with Bushold and 26Ω Series Resistor in Outputs September 2001 Revised February 2002 74ALVCH162244 Low Voltage 16-Bit Buffer/Line Driver with Bushold and 26Ω 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 circuitry, 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 26Ω series resistors in the outputs. This design reduces line noise in applications such as memory address drivers, clock drivers, 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.

The device is nibble (4 bits) controlled with each nibble functioning identically, but independent of each other. The control pins may be shorted together to obtain full 16-bit operation.The 3-STATE outputs are controlled by an Output Enable (OEn) input. When OEn is LOW, the outputs are in the 2-state mode. When OEn is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the inputs.
