CD40106BM hex Schmitt-trigger inverter — CMOS, SOP-14 SMD package round Controlled via AT commandsThe CD40106BM is a CMOS hex Schmitt trigger inverter IC in an SOP 14 surface mount package. It contains six independent inverting buffers, each with a Schmitt trigger input that provides hysteresis for clean, noise immune switching. The difference between the positive going threshold (VP) and the negative going threshold (VN) defines the hysteresis voltage (VH), making it ideal for conditioning slow or noisy input signals into clean digital
