74VCX00 Low Voltage Quad 2-Input NAND Gate with 3.6V Tolerant Inputs and Outputs

July 1999
Revised July 1999

General Description

The VCX00 contains four 2 -input NAND gates. This prod­uct is designed for low voltage (1.65V to 3.6V) V

tions with I/O compatibility up to 3.6V.
The VCX00 is fabricated with an advanced CMOS technol-

ogy to achieve high-speed o peratio n while maintai ning low
CMOS power dissipation.

Note 1: The Absolute Maximum Ratings are those values beyond which
the safety of the dev ice cannot be guaranteed. T he device sh ould 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 condi­tions for actual device operation.

Absolute Maximum Rating must be observed.
