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 26? 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.
