M74HC14集成電路（IC）的信號開關多路復用器解碼器規(guī)格書PDF中文資料

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 可用于對以數字格式表示數據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
