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.
Features
