M74HC14 HEX SCHMITT INVERTER ■ ■ ■ ■ ■ ■ ■ HIGH SPEED: tPD =12ns (TYP.) at VCC = 6V LOW POWER DISSIPATION: ICC = 1µA(MAX.) at TA=25°C HIGH NOISE IMMUNITY: VH = 1.2 V (TYP.) AT VCC = 6 V SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 14 DESCRIPTION The M74HC14 is an high speed CMOS HEX SCHMITT INVERTER fabricated with silicon gate C2MOS technology. Pin configuration and function are the same as those of the M74HC04 but all inputs have 20% Vcc hysteresis level. This, together with its schmitt trigger function, allows it to be used on line receivers with slow rise/fall input signals.
