Features, Applications

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.


s Wide supply voltage range: s Low power: 0.4 VCC (typ.) s Hysteresis: 15V s High noise immunity: 0.70 VCC (typ.) TTL compatibility: 0.2 VCC guaranteed 0.4 VCC (typ.): 0.2 VCC guaranteed

Order Number MM74C14M MM74C14N Package Number M14A N14A Package Description 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide

Devices also available in Tape and Reel. Specify by appending suffix letter "X" to the ordering code.

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.

Min/Max limits apply across the guaranteed temperature range unless otherwise noted Symbol Parameter Conditions CMOS TO CMOS VT+ Positive Going Threshold Voltage VCC = 5V VCC = 10V VCC = 15V VT- Negative Going Threshold Voltage VCC = 5V VCC = 10V VCC = 15V VT+ VT- Hysteresis VCC = 5V VCC = 10V VCC IIN(1) IIN(0) ICC Logical "1" Output Voltage Logical "0" Output Voltage Logical "1" Input Current Logical "0" Input Current Supply Current VCC -10 A VCC -10 A VCC 10 A VCC 10 A VCC = 15V, VIN = 15V VCC = 15V, VIN = 0V VCC = 15V, VIN = 0V/15V VCC = 5V, VIN = 2.5V (Note 2) VCC = 10V, VIN = 5V (Note 2) VCC = 15V, VIN = 7.5V (Note 2) CMOS/LPTTL INTERFACE VOUT(1) VOUT(0) Logical "1" Input Voltage Logical "0" Input Voltage Logical "1" Output Voltage Logical "0" Output Voltage VCC = 5V VCC 5V 74C, VCC A 74C, VCC A V Min Typ Max Units
