74LVX02 Low Voltage Quad 2-Input NOR Gate
May 1993
Revised February 2005
74LVX02
Low Voltage Quad 2-Input NOR Gate
General Description
The LVX02 contains four 2-input NOR gates. The inputs
tolerate voltages up to 7V allowing the interface of 5V sys-
tems to 3V systems.
Features
s
Input voltage level translation from 5V to 3V
s
Ideal for low power/low noise 3.3V applications
s
Guaranteed simultaneous switching noise level and
dynamic threshold performance

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 ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Note 3:
Unused inputs must be held HIGH or LOW. They may not float.
