74VCX162240 Low Voltage 16-Bit Inverting Buffer/Line Driver with 3.6V Tolerant Inputs and Outputs and 26:
Series Resistors in Outputs
74VCX162240
Low Voltage 16-Bit Inverting Buffer/Line Driver
with 3.6V Tolerant Inputs and Outputs
and 26: Series Resistors in Outputs
General Description
The VCX162240 contains sixteen 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 74VCX162240 is designed for low voltage (1.4V to
3.6V) V
CC
applications with I/O capability up to 3.6V. The
74VCX162240 is also designed with 26
series resistors in
the outputs. This design reduces line noise in applications
such as memory address drivers, clock drivers, and bus
transceivers/transmitters.
The 74VCX162240 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

through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.

Functional Description
The 74VCX162240 contains sixteen inverting buffers with
3-STATE outputs. The device is nibble (4 bits) controlled
with each nibble functioning identically, but independent of
each other. The control pins may be shorted together to
obtain full 16-bit operation.The 3-STATE outputs are con-
trolled by an Output Enable (OE
n
) input. When OE
n
is
LOW, the outputs are in the 2-state mode. When OE
n
is
HIGH, the standard outputs are in the high impedance
mode but this does not interfere with entering new data into
the inputs.

Absolute Maximum Ratings(Note 2) Recommended Operating
Conditions
(Note 4)
Note 2: The Absolute Maximum Ratings are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the Absolute Maximum Rat-
ings. The “Recommended Operating Conditions” table will define the condi-
tions for actual device operation.
Note 3: I

Absolute Maximum Rating must be observed.
Note 4: Floating or unused inputs must be held HIGH or LOW.
