74LVX86
Low Voltage Quad 2-Input Exclusive-OR Gate
General Description
The LVX86 contains four 2-input exclusive-OR gates. The
inputs tolerate voltages up to 7V allowing the interface of
5V systems 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
Ordering Code:
Devices also available in Tape and Reel. Specify by appending suffix letter "X" to the ordering code.

Conditions
(Note 2)
Note 1: 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 2: Unused inputs must be held HIGH or LOW. They may not float.
