Overview
The CD40106B, produced by Texas Instruments, is a CMOS Hex Schmitt-Trigger Inverter device. It consists of six independent inverters, each with a Schmitt-Trigger input. This device is designed to handle noisy or slow input signals by providing a minimum separation between positive and negative switching thresholds, thus preventing issues like oscillation or excessive current consumption. The CD40106B operates over a wide voltage range from 3 V to 18 V and is rated for ambient temperature operation from –55°C to +125°C.
