74LCXH162244

Low Voltage 16-Bit Buffer/Line Driver with Bushold

and 26: Series Resistors in Outputs

General Description

The LCXH162244 contains sixteen non-inverting buffers

with 3-STATE outputs designed to be employed as a mem-

ory and address driver, clock driver, or bus oriented trans-

mitter/receiver. The device is nibble controlled. Each nibble

has separate 3-STATE control inputs which can be shorted

together for full 16-bit operation.

The LCXH162244 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.

In addition, the outputs include equivalent 26: (nominal)

series resistors to reduce overshoot and undershoot and

are designed to sink/source up to 12 mA at VCC 3.0V.

The LCXH162244 is designed for low voltage (2.5V or

3.3V) VCC applications with capability of interfacing to a 5V

signal environment.

The LCXH162244 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing CMOS low power dissipation.
