MM54HCT157 MM74HCT157 Quad 2-Input Multiplexer MM54HCT158 MM74HCT158 Quad 2-Input Multiplexer (Inverted Output) February 1988 MM54HCT157 MM74HCT157 Quad 2-Input Multiplexer MM54HCT158 MM74HCT158 Quad 2-Input Multiplexer (Inverted Output) General Description These high speed QUAD 2-to-1 line data selector multiplexers utilize advanced silicon-gate CMOS technology They possess the high noise immunity and low power consumption of standard CMOS integrated circuits as well as the ability to drive 10 LS-TTL loads These devices each consist of four 2-input digital multiplexers with common select and OUTPUT ENABLE inputs On the MM54HCT157 MM74HCT157 when the OUTPUT ENABLE input is at logical ‘‘0’’ the four outputs assume the values as selected from the inputs When the OUTPUT ENABLE input is at a logical ‘‘1’’ the outputs assume logical ‘‘0’’ The MM54HCT158 MM74HCT158 operates in the same manner except that its outputs are inverted Select decoding is done internally resulting in a single select input only If enabled the select input determines whether the A or B inputs get routed to their corresponding Y outputs The 54HCT 74HCT logic family is functionally as well as pin-out compatible with the standard 54LS 74LS logic family All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground Features Y Y Y Y Y Y Typical propagation

voltages (VOH and VOL) occur for HCT 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 74HCT TA eb40 to 85 C 54HCT TA eb55 to 125 C Units Guaranteed
