MM54HC151/MM74HC151 8-ChannelDigital MulTIplexerGeneral DescripTIonThis high speed Digital mulTIplexer uTIlizes advanced silicongateCMOS technology. Along with the high noise immunityand low power dissipation of standard CMOS integrated circuits,it possesses the ability to drive 10 LS-TTL loads. TheMM54HC151/MM74HC151 selects one of the 8 data sources,depending on the address presented on the A, B, and Cinputs. It features both true (Y) and complement (W) outputs.The STROBE input must be at a low logic level toenable this multiplexer. A high logic level at the STROBEforces the W output high and the Y output low.The 54HC/74HC logic family is functionally as well as pinoutcompatible with the standard 54LS/74LS logic family.All inputs are protected from damage due to static dischargeby internal diode clamps to VCC and ground.FeaturesY Typical propagation delaydata select to output Y: 26 nsY Wide operating supply voltage range: 2±6VY Low input current: 1 mA maximumY Low quiescent supply current: 80 mA maximum (74HC)Y High output drive current: 4 mA minimum
