74VCXH162244
Low Voltage 16-Bit Buffer/Line Driver with Bushold
and 26Series Resistor in Outputs
General Description
The VCXH162244 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 VCXH162244 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 74VCXH162244 is also designed with 26series
resistors in the outputs. This design reduces line noise in
applications such as memory address drivers, clock driv-
ers, and bus transceivers/transmitters.
The 74VCXH162244 is designed for low voltage (1.65V to
3.6V) VCC applications with output capability up to 3.6V.
The 74VCXH162244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
