CD40106BC
Hex Schmitt Trigger
General Description
The CD40106BC Hex Schmitt Trigger is a monolithic com-
plementary MOS (CMOS) integrated circuit constructed
with N and P-channel enhancement transistors. The posi-
tive and negative-going threshold voltages, V
T+
and V
T−
,
show low variation with respect to temperature (typ
0.0005V/
°
C at V
DD
=
10V), and hysteresis, V

All inputs are protected from damage due to static dis-
charge by diode clamps to V
DD
and V
SS
.

Note 1:
“Absolute Maximum Ratings” are those values beyond which the
safety of the device cannot be guaranteed. They are not meant to imply
that the devices should be operated at these limits. The table of “Recom-
mended Operating Conditions” and “Electrical Characteristics” provides
conditions for actual device operation.
