M74HC14屬于集成電路（IC）的信號開關多路復用器解碼器。由意法半導體集團制造生產(chǎn)的M74HC14信號開關，多路復用器，解碼器邏輯型信號開關、多路復用器和編碼器 IC 可用于對以數(shù)字格式表示數(shù)據(jù)的電信號進行路由和選擇。這些器件與設計用于模擬信號的類似產(chǎn)品有所不同，它們保留的信息表示為兩個電狀態(tài)之一，而不是兩個外部界限內(nèi)的無窮變化量。

DESCRIPTION

The M54/74HC14 is a high speed CMOS HEX SCHMITT INVERTER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. Pin configuration and function are the same as those of the HC04 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 = 11 ns (TYP.) AT VCC = 5 V

■ LOW POWER DISSIPATION ICC = 1 μA (MAX.) AT TA = 25 °C

■ HIGH NOISE IMMUNITY VH = 1.1 V (TYP.) AT VCC = 5 V

■ OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS

■ SYMMETRICAL OUTPUT IMPEDANCE ?IOH? = IOL = 4 mA (MIN.)

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

■ WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V

■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS14
