CD40106 - Hex Schmitt Trigger Inverter IC Toggle Switches 5V 1 Channel SSR ModuleCD40106 Hex Schmitt Trigger Inverter IC The CD40106 IC consists of six Schmitt Trigger inputs. Each circuit functions as an inverter with Schmitt Trigger input. The trigger switches at different points for positive and negative going signals. The difference between the positive going voltage (VP) and the negative going voltage (VN) is defined as hysteresis voltage (VH). A Schmitt trigger input means that the threshold voltage for going from a HIGH to
