Inverting Comparator With Hysteresis

Comparator with hysteresis (Schmidt trigger) can be built using  LM339, LM239, LM2901, LM2901V, NCV2901, or MC3302  quad single supply comparator integrated circuit chips. Here is the circuit’s schematic diagram and formula: This circuit’s output will swing to high or low using two threshold values. If the last output is high, then the output can be changed to low if the […]
