DESCRIPTION  
The 74V1G14 is an advanced high-speed CMOS  
SINGLE SCHMITT INVERTER fabricated with  
sub-micron silicon gate and double-layer metal  
interface 5V to 3V. Pin configuration and function  
are the same as those of the 74V1G04 but the  
74V1G14 has hysteresis.  
2
wiring C MOS technology.  
This together with its schmitt trigger function  
allows it to be used on line receivers with slow  
rise/fall input signals.  
The internal circuit is composed of 3 stages  
including buffer output, which provide high noise  
immunity and stable output.  
The input is equipped with protection circuits  
against static discharge, giving it ESD immunity  
and transient excess voltage.  
Power down protection is provided on input and 0  
to 7V can be accepted on input with no regard to  
the supply voltage. This device can be used to
