DESCRIPTION

The M54/74HC151 is a high speed CMOS 8 CHANNEL MULTIPLEXER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low powerconsumption. It provides, in onepackage, the ability to select one bit of data from up to eight sources. The HC151 can be used as a universal function generator to generate any logic function of four variables.

■ HIGH SPEED tPD = 15 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 54/74LS151

M74HC151属于集成电路（IC） > 信号开关，多路复用器，解码器。意法半导体（ST）集团制造生产的M74HC151信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。
