MM74C14

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 Ordering Code: Order Number MM74C14M MM74C14N Package Number M14A N14A Package Description 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150” Narrow 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide Devices also available in Tape and Reel.
