Overview
The CD40106BM is a CMOS HEX SCHMITT TRIGGER integrated circuit produced by Texas Instruments. This device consists of six Schmitt-Trigger inputs, each functioning as an inverter with Schmitt-Trigger input. The Schmitt-Trigger inputs provide hysteresis, which enhances noise immunity by ensuring the trigger switches at different points for positive- and negative-going signals. The CD40106BM is available in various packaging options, including SOIC (D) with 14 pins, and is rated for operation over an ambient temperature range of –55°C to +125°C.
