MM74C14 Hex Schmitt Trigger
October 1987 Revised January 1999
MM74C14 Hex Schmitt Trigger
General Description
The MM74C14 Hex Schmitt Trigger is a monolithic complementary 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+ - VT- 0.2 VCC is guaranteed. All inputs are protected from damage due to static discharge by diode clamps to VCC and GND.
Features
s Wide supply voltage range: s High noise immunity: 0.4 VCC (typ.) s Hysteresis: 3.0V to 15V 0.70 VCC (typ.) s Low power: TTL compatibility: 0.2 VCC guaranteed 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 Temperature Range" they are not meant to imply that the devices should be operated at these limits. The Electrical Characteristics tables provide conditions for actual device operation.
