Hex inverting Schmitt trigger
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.
