HEF40106 Datasheet PDF

●The HEF40106BT is a Hex Inverting Schmitt-trigger, each input has a Schmitt-trigger circuit. The inverting buffer switches at different points for positive-going and negative-going signals. The difference between the positive voltage (VT+) and the negative voltage (VT-) is defined as hysteresis voltage (VH). The HEF40106B may be used for enhanced noise immunity or to "square up" slowly changing waveforms. It operates over a recommended VDD power supply range of 3 to 15V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS or another input.
