74VCXH16244
Low Voltage 16-Bit Buffer/Line Driver with Bushold
General Description
The VCXH16244 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 VCXH16244 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 74VCXH16244 is designed for low voltage (1.65V to
3.6V) VCC applications with output capability up to 3.6V.
The 74VCXH16244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
