M74HC14 Hex Schmitt inverter Features ■ ■ ■ ■ ■ ■ ■ High speed: tPD =12 ns (typ.) at VCC = 6 V Low power dissipation: ICC = 1 μA (max.) at TA = 25 °C High noise immunity: VH = 1.2 V (typ.) at VCC = 6 V Symmetrical output impedance: |IOH| = IOL = 4 mA (min.) Balanced propagation delays: tPLH tPHL Wide operating voltage range: VCC (opr) = 2 to 6 V Pin and function compatible with 74 series 14 TSSOP14 DIP-14 SO-14 Description The M74HC14 is a high speed CMOS hex Schmitt inverter fabricated with silicon gate C2MOS technology. Pin configuration and functions are the same as those of the M74HC04 but all the inputs have 20% VCC hysteresis level. This, together with its Schmitt trigger function, allows the device to be used on line receivers with slow rise/fall input signals. All inputs are equipped with protection circuits against static discharge and transient excess voltage. Table 1.
