MM74C914
Hex Schmitt Trigger with Extended Input Voltage
General Description
The MM74C914 is a monolithic CMOS Hex Schmitt trigger
with special input protection scheme. This scheme allows
the input voltage levels to exceed V
CC
or ground by at least
10V (V
CC
25V to GND
+
25V), and is valuable for applica-
tions involving voltage level shifting or mismatched power
supplies.
The positive and negative-going threshold voltages, V
T
+
and V
T
, show low variation with respect to temperature
(typ 0.0005V/
°
C at V
CC
=
10V). And the hysteresis, V

T
≥
0.2 V
