1 / 14 page May 2008 Rev 2 1/14 14 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 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. SO-14 TSSOP14 DIP-14 Table 1.
