CD40106BM hex Schmitt-trigger inverter — CMOS, SOP-14 SMD package

The 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 (V_P) and the negative-going threshold (V_N) defines the hysteresis voltage (V_H), making it ideal for conditioning slow or noisy input signals into clean digital transitions.

Rated for −55°C to +125°C operation, the CD40106BM is suitable for industrial and automotive environments. It is a direct SMD equivalent of the CD40106B in DIP packaging.
