74LCXH16244
Low Voltage 16-Bit Buffer/Line Driver with Bushold
General Description
The LCXH16244 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 LCXH16244 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.
The LCXH16244 is designed for low voltage (2.5V or 3.3V)

applications with capability of interfacing to a 5V signal
environment.
The LCXH16244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
