MM54HCT157/MM74HCT157 Quad 2-Input Multiplexer MM54HCT158/MM74HCT158 Quad 2-Input Multiplexer (Inverted Output) General Description 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. 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.

Note 4: For a power supply of 5V g 10% the worst case output 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. 2 AC Electrical Characteristics VCC e 5V, TA e 25§ C, CL e 15 pF, tr e tf e 6 ns Typ Guaranteed Limit Units Maximum Propagation Delay, Data to Output 14 20 ns tPHL, tPLH Maximum Propagation Delay, Select to Output 14 20 ns tPHL, tPLH Maximum Propagation Delay, Strobe to Output 12 18 ns Symbol Parameter tPHL, tPLH Conditions AC Electrical Characteristics VCC e 5V g 10%, CL e 50 pF, tr e tf e 6 ns (unless otherwise specified) Symbol Parameter Conditions TA e 25§ C Typ 74HCT TA eb40 to 85§ C 54HCT TA eb55 to 125§ C Units Guaranteed Limits tPHL, tPLH Maximum Propagation Delay, Data to Output 13 22 28 33 ns tPHL, tPLH Maximum Propagation Delay, Select to Output 15 27 34 41 ns tPHL, tPLH Maximum Propagation Delay, OUTPUT ENABLE to Output 14 25 31 38 ns tTLH, tTHL Maximum Output Rise and Fall Time 8 15 19 22 ns CIN Maximum Input Capacitance 5 10 10 10 pF CPD Power Dissipation Capacitance (Note 5) 48 pF Note 5: CPD determines the no load dynamic power consumption, PD e CPD VCC2 f a ICC VCC, and the no load dynamic current consumption, IS e CPD VCC f a ICC. 3 Logic Diagrams ’HCT157 TL/F/5741 – 3 ’HCT158 TL/F/5741 – 4 4 Physical Dimensions inches (millimeters) Ceramic Dual-In-Line Package (J) Order Number MM54HCT157J, MM54HCT158J, MM74HCT157J or MM74HCT158J NS Package Number J16A 5 MM54HCT157/MM74HCT157 Quad 2-Input Multiplexer MM54HCT158/MM74HCT158 Quad 2-Input Multiplexer (Inverted Output) Physical Dimensions inches (millimeters) (Continued) Molded Dual-In-Line Package (N) Order Number MM74HCT157N or MM74HCT158N NS Package Number N16E LIFE SUPPORT POLICY NATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT OF NATIONAL SEMICONDUCTOR CORPORATION.
