Overview
The CD40106BMG4 is a CMOS Hex Schmitt-Trigger Inverter produced by Texas Instruments. This device consists of six independent Schmitt-Trigger input inverters, each performing the Boolean function Y = A in positive logic. The CD40106B series, including the CD40106BMG4, is designed to handle noisy or slow input signals, providing a minimum separation between positive and negative switching thresholds to prevent issues like oscillation or excessive current consumption.
