MM54C14 MM74C14 Hex Schmitt Trigger February 1988 MM54C14 MM74C14 Hex Schmitt Trigger General Description The MM54C14 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 a and VTb show low variation with respect to temperature (typ 0 0005V C at VCC e 10V) and hysteresis VT a b VTb t 0 2 VCC is guaranteed All inputs are protected from damage due to static discharge by diode clamps to VCC and GND Features Y Y Y Y Wide supply voltage range High noise immunity Low power TTL compatibility Hysteresis 3 0V to 15V 0 70 VCC (typ ) 0 4 VCC (typ ) 0 2 VCC guaranteed 0 4 VCC (typ ) 0 2 VCC guaranteed Connection Diagram Dual-In-Line Package TL F 5879 – 1
