74ALVCH162244 Datasheet – 16-Bit Buffer / Line Driver

What is 74ALVCH162244?

This is a 16-bit buffer/line driver IC designed to operate at a low voltage of 1.65V to 3.6V. It features 16 output channels, each of which can sink or source up to 24mA of current, making it suitable for driving a variety of loads, including capacitive loads.

The 74ALVCH162244 is designed to work in a variety of applications, such as memory interfacing, bus buffering, and signal distribution. It has a tri-state output, which allows the outputs to be disconnected from the bus, making it suitable for bus-oriented applications.

Function: Low Voltage 16-Bit Buffer/Line Driver with Bushold and 26Ω Series Resistor in Outputs

Package: TSSOP 48 Pin type

Manufacturer: Fairchild Semiconductor


74ALVCH162244 datasheet



The 74ALVCH162244 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 ransceivers/transmitters. The 74ALVCH162244 is designed for low voltage (1.65V to 3.6V) VCCapplications 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.
