DESCRIPTION
The 74VHC86 is an advanced high-speed CMOS
QUAD EXCLUSIVE OR GATE fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage. This device can be
used to interface 5V to 3V.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
