M74HC14屬于集成電路（IC）的信號(hào)開關(guān)多路復(fù)用器解碼器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的M74HC14信號(hào)開關(guān)，多路復(fù)用器，解碼器邏輯型信號(hào)開關(guān)、多路復(fù)用器和編碼器 IC 可用于對(duì)以數(shù)字格式表示數(shù)據(jù)的電信號(hào)進(jìn)行路由和選擇。這些器件與設(shè)計(jì)用于模擬信號(hào)的類似產(chǎn)品有所不同，它們保留的信息表示為兩個(gè)電狀態(tài)之一，而不是兩個(gè)外部界限內(nèi)的無窮變化量。

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.

All inputs are equipped with protection circuits against static discharge and transient excess

voltage.

■ 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
