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.
