74VCX32244
Low Voltage 32-Bit Buffer/Line Driver
with 3.6V Tolerant Inputs and Outputs
General Description
The VCX32244 contains thirty-two 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 8-bit, 16-bit or full 32-bit operation.
The 74VCX32244 is designed for low voltage (1.2V to
3.6V) V
CC
applications with I/O capability up to 3.6V.
The 74VCX32244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.

Note 1:
To ensure the high-impedance state during power up or power
down, OE should be tied to V
CC
through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.
