74LVX86T  
It has better speed performance at 3.3V than 5V  
LS-TTL family combined with the true CMOS low  
power consumption.  
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 interface5V to 3V.  
OPERATING VOLTAGERANGE:  
VCC (OPR)= 2V to 3.6V(1.2VDataRetention)  
PIN AND FUNCTION COMPATIBLEWITH  
74 SERIES86  
IMPROVED LATCH-UP IMMUNITY  
DESCRIPTION  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.  
The 74LVX86 is a low voltage CMOS QUAD  
EXCLUSIVE OR GATE fabricated with  
sub-micron silicon gate and double-layer metal  
wiring C2MOS technology. It is ideal for low  
power and low noise 3.3V applications.
