immunity and stable output.  
OPERATING VOLTAGERANGE:  
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.  
VCC (OPR)= 2V to 5.5V  
PIN AND FUNCTION COMPATIBLEWITH  
74 SERIES20  
IMPROVED LATCH-UP IMMUNITY  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.  
DESCRIPTION  
The 74VHC20 is an advanced high-speed CMOS  
DUAL 4-INPUT NAND GATE fabricated with  
sub-micron silicon gate and double-layer metal  
wiring C2MOS technology.  
The internal circuit is composed of 3 stages  
including buffer output, which provide high noise
