74VCX08 Low Voltage Quad 2-Input AND Gate with 3.6V Tolerant Inputs and Outputs

July 1999
Revised February 2005

General Description

The VCX08 contains four 2-input AN D gates. Thi s product
is designed for low voltage (1.2V to 3. 6V ) V

with I/O compatibility up to 3.6V
The VCX08 is fabricated with an advanced CMOS technol-

ogy to achieve high-sp eed ope ration wh ile m aintainin g low
CMOS power dissipation.
