MM54HCT151 MM54HCT151 MM74HCT151 MM74HCT151 8-Channel Digital Multiplexer General Description This high speed Digital multiplexer utilizes advanced silicongate CMOS technology Along with the high noise immunity and low power dissipation of standard CMOS integrated circuits it possesses the ability to drive 10 LS-TTL loads The MM54HCT151 MM54HCT151 MM74HCT151 MM74HCT151 selects one of the 8 data sources depending on the address presented on the A B and C inputs It features both true (Y) and complement (W) outputs The STROBE input must be at a low logic level to enable this multiplexer A high logic level at the STROBE forces the W output high and the Y output low MM54HCT MM54HCT MM74HCT MM74HCT devices are intended to interface between TTL and NMOS components and standard CMOS Connection and Logic Diagrams devices These parts are also plug-in replacements for LSTTL devices and can be used to reduce power consumption in existing designs Features Y Y Y Y Y Typical propagation

at 4 5V Thus the 4 5V values should be used when designing with this supply Worst case VIH and VIL occur at VCC e 5 5V and 4 5V respectively (The VIH value at 5 5V is 3 85V ) The worst case leakage current (IIN ICC and IOZ) occur for CMOS at the higher voltage and so the 6 0V values should be used 2 AC Electrical Characteristics VCC e 5V TA e 25 C CL e 15 pF tr e tf e 6 ns Conditions Parameter
