General description
The HEF40106B provides six inverting buffers. 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 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input. It is also suitable for use over both the industrial (-40℃ to +85℃) and automotive ( -40℃ to +125 ℃) temperature ranges.
