Overview
The CD40106B, specifically the CD40106BM96E4, is a CMOS Hex Schmitt-Trigger Inverter produced by Texas Instruments. This device consists of six independent inverters, each with a Schmitt-Trigger input. The Schmitt-Trigger inputs are designed to provide a minimum separation between positive and negative switching thresholds, making them ideal for handling noisy or slow input signals. This feature helps in preventing oscillation or excessive current consumption. The CD40106B operates over a wide voltage range from 3 V to 18 V and is rated for an ambient temperature range of –55°C to +125°C, making it versatile for various applications.
