74ALVCH16244 Low Voltage 16-Bit Buffer/Line Driver with Bushold
September 2001
Revised February 2002
74ALVCH16244
Low Voltage 16-Bit Buffer/Line Driver with Bushold
General Description
The ALVCH16244 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 ALVCH16244 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 74ALVCH16244 is designed for low voltage (1.65V to
3.6V) V
CC
applications with output capability up to 3.6V.
The 74ALVCH16244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
