SCHMITT TRIGGERS  
DUAL GATE/HEX INVERTER  
The SN54LS/74LS13 and SN54LS/74LS14 contain logic gates/inverters  
which accept standard TTL input signals and provide standard TTL output  
levels. They are capable of transforming slowly changing input signals into  
sharplydefined, jitter-freeoutputsignals. Additionally, theyhavegreaternoise  
margin than conventional inverters.  
Each circuit contains a Schmitt trigger followed by a Darlington level shifter  
and a phase splitter driving a TTL totem pole output. The Schmitt trigger uses  
positive feedback to effectively speed-up slow input transitions, and provide  
different input threshold voltages for positive and negative-going transitions.  
This hysteresis between the positive-going and negative-going input  
thresholds (typically 800 mV) is determined internally by resistor ratios and is  
essentially insensitive to temperature and supply voltage variations.
