8.1 Overview

The CD40106B device contains six independent inverters with schmitt trigger inputs.. They perform the Boolean function Y = A in positive logic.

Schmitt-Trigger inputs are designed to provide a minimum separation between positive and negative switching thresholds. This allows for noisy or slow inputs that would cause problems such as oscillation or excessive current consumption.

8.3 Feature Description

The CD40106B has standardized symmetrical output characteristics and a wide operating voltage from 3 V to
18 V with quiescent current of 20 µA tested at 20 V. These devices have transition times of t_TLH = t_THL = 50 ns (typical) at 10 V. The operating temperature is from –55°C to +125°C. Schmitt trigger inputs on this device support slow or noisy input signals.
