11.24.1. General Description
The 74LX1G86 is a low voltage CMOS SINGLE 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.
