DESCRIPTION

Each circuit of the HEF40106B functions as an inverter

with Schmitt-trigger action. The Schmitt-trigger switches at

different points for the positive and negative-going input

signals. The difference between the positive-going voltage

(VP) and the negative-going voltage (VN) is defined as

hysteresis voltage (VH).

This device may be used for enhanced noise immunity or

to “square up” slowly changing waveforms.
