M74HC42RM13TR集成電路（IC）的信號開關(guān)多路復(fù)用器解碼器規(guī)格書PDF中文資料

M74HC42RM13TR屬于集成電路（IC）的信號開關(guān)多路復(fù)用器解碼器。由意法半導(dǎo)體集團制造生產(chǎn)的M74HC42RM13TR信號開關(guān)，多路復(fù)用器，解碼器邏輯型信號開關(guān)、多路復(fù)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(shè)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 M54/74HC42 is a high speed CMOS BCD-TO-DECIMAL DECODER fabricated in silicon gate C2MOS technology.

It has the same high speed performance of LSTTL combined with true CMOS low power consumption.

■ HIGH SPEED tPD = 13 ns (TYP.) AT VCC = 5 V

■ LOW POWER DISSIPATION ICC = 4 μA (MAX.) AT TA = 25 °C

■ HIGH NOISE IMMUNITY VNIH = VNIL = 28 VCC (MIN.)

■ 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 54/74LS42
