The MC140106BCP is a Hex Schmitt-Trigger Inverter. It is part of the MC14000 series of CMOS logic integrated circuits manufactured by Motorola (later Freescale, now NXP). This device contains six independent inverters, each with Schmitt-trigger action. The Schmitt-trigger input provides different threshold voltages for rising and falling input signals, resulting in hysteresis. This hysteresis makes the device suitable for applications requiring noise immunity and signal conditioning, such as waveform shaping, pulse squaring, and switch debouncing.

Additional Details

The MC140106BCP contains six identical inverters. Each inverter has a Schmitt-trigger input, characterized by its upper (VT+) and lower (VT-) threshold voltages. When the input voltage exceeds VT+, the output switches to a logic low. When the input voltage falls below VT-, the output switches to a logic high. The difference between VT+ and VT- is the hysteresis voltage, which prevents oscillations and provides noise immunity. The device is fabricated using CMOS technology. The operating voltage range is typically between 3V and 15V. It's usually available in a through-hole DIP (Dual In-line Package). It is a versatile component often employed in digital circuits to improve signal quality and prevent unwanted switching.
