M74HC14

Hex Schmitt inverter

Features

■High speed:

tPD =12 ns (typ.) at VCC = 6 V

■Low power dissipa tion:

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 compat ible 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 de vice to be used on line receiv ers with

slow rise/fall input signals.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.

capacitance(1) 5.0 fIN = 1 0 MHz 28 pF

1. CPD is defined as the value of the IC’s internal e quivalent capacitance which is calculated from the operating current

consumption without load. (Refer to test circuit). Average operating current can be obtained by the following equation:

ICC(opr) = CPD x VCC x fIN + ICC/6(per gate).
