Overview
The CD40106BMT, produced by Texas Instruments, is a CMOS Hex Schmitt-Trigger Inverter. This device consists of six independent Schmitt-Trigger input inverters, each performing the Boolean function Y = A in positive logic. It is designed to handle noisy or slow input signals, providing a minimum separation between positive and negative switching thresholds to prevent issues such as oscillation or excessive current consumption. The CD40106BMT operates over a wide voltage range from 3 V to 18 V and is rated for ambient temperatures from –55°C to +125°C, making it versatile for various applications.
