MM74C14
Hex Schmitt Trigger
General Description
The MM74C14 Hex Schmitt Trigger is a monolithic comple-
mentary MOS (CMOS) integrated circuit constructed with
N- and P-channel enhancement transistors. The positive
and negative going threshold voltages VT+ and VT, show
low variation with respect to temperature (typ. 0.0005V/°C
at VCC = 10V), and hysteresis, VT+ VT0.2 VCC is guar-
anteed.
All inputs are protected from damage due to static dis-
charge by diode clamps to VCC and GND.
Features
s Wide supply voltage range: 3.0V to 15V
s High noise immunity: 0.70 VCC (typ.)
s Low power: TTL compatibility:
0.4 VCC (typ.) 0.2 VCC guaranteed
s Hysteresis: 0.4 VCC (typ.): 0.2 VCC guaranteed

Note 1: “Absolute Maximum Ratings” are those values beyond which the
safety of the device cannot be guaranteed. Except for “Operating Tempera-
ture Range” they are not meant to imply that the devices should be oper-
ated at these limits. The Electrical Characteristics tables provide conditions
for actual device operation.
