wiring C2MOS technology. It is ideal for low  
power applications mantaining high speed  
operation similar to equivalent Bipolar Schottky  
TTL.  
The internal circuit is composed of 3 stages  
including buffer output, which enables high noise  
immunity and stable output.  
VCC (OPR) = 2V to 6V  
PIN AND FUNCTION COMPATIBLE WITH  
74 SERIES 20  
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 AC20 is an advanced high-speed CMOS  
DUAL 4-INPUT NAND GATE fabricated with  
sub-micron silicon gate and double-layer metal
