74VCX32
Low Voltage Quad 2-Input OR Gate with
3.6V Tolerant Inputs and Outputs
General Description
The VCX32 contains four 2-input OR gates. This product is
designed for low voltage (1.2V to 3.6V) V
CC
applications
with I/O compatibility up to 3.6V.
The VCX32 is fabricated with an advanced CMOS technol-
ogy to achieve high-speed operation while maintaining low
CMOS power dissipation.

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:

Absolute Maximum Rating must be observed.
Note 4:

50 pF, add approximately 300 ps to the AC maximum specification.
Note 6:
Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (t
OSHL
) or LOW-to-HIGH (t
OSLH
).
