40106 IC hex Schmitt Trigger inverter
The CD40106BE is a hex Schmitt Trigger inverter IC designed to provide precise logic level switching with hysteresis. Unlike standard inverters, this IC incorporates Schmitt trigger inputs, which help clean up noisy or slow input signals, ensuring sharp and stable transitions at the output.
Each of the six independent inverters inside the IC operates with built-in hysteresis, making it especially useful in signal conditioning, waveform shaping, and oscillator circuits. It is highly suitable for applications involving switches, sensors, or analog signal inputs that need conversion to clean digital logic levels.
