74LVX32
Low Voltage Quad 2-Input OR Gate
General Description
The LVX32 contains four 2-inp ut OR gates . T he in puts t olerate voltages up to 7V allowing the interface of 5V systems to 3V systems.
Features
■ Input voltage level translation from 5V to 3V
■ Ideal for low power/low noise 3.3V applications
■ Guaranteed simultaneous switching noise level and
dynamic threshold performance
Ordering Code:
Devices also availab le in Tape and Reel. Specify by appending su ffix let te r “X” to the ordering code.

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
(Note 2)
Note 1: The “Absolute Maximum Ratin gs” are those v alues beyon d 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 ratings.
The “Recommend ed O peratin g Cond itions” t able w ill defin e the co ndition s
for actual device operation.
Note 2: Unused inputs must be held HIGH or LOW. They may not float.
