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.

If a Schmitt trigger is driven via a high impedance (R > 1 kΩ) then it is necessary to incorporate a capacitor C of such
value that: , otherwise oscillation can occur on the edges of a pulse.
C
p
is the external parasitic capacitance between input and output; the value depends on the circuit board layout.
