CD54/74HC157, CD54/74HCT157, CD54/74HC158, CD54/74HCT158 Data sheet acquired from Harris Semiconductor SCHS153C High-Speed CMOS Logic Quad 2-Input Multiplexers September 1997 - Revised October 2003 Features Description • Common Select Inputs The ’HC157, ’HCT157, ’HC158, and ’HCT158 are quad 2input multiplexers which select four bits of data from two sources under the control of a common Select input (S). The Enable input (E) is active Low. When (E) is High, all of the outputs in the 158, the inverting type, (1Y-4Y) are forced High and in the 157, the non-inverting type, all of the outputs (1Y-4Y) are forced Low, regardless of all other input conditions. • Separate Enable Inputs • Buffered inputs and Outputs • Fanout (Over Temperature Range) - Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads - Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads • Wide Operating Temperature Range . . . -55oC to 125oC Moving data from two groups of registers to four common output buses is a common use of these devices. The state of the Select input determines the particular register from which the data comes. They can also be used as function generators. • Balanced Propagation Delay and Transition Times • Significant Power Reduction Compared to LSTTL Logic ICs • HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30%of VCC at VCC = 5V Ordering Information • HCT Types - 4.5V to 5.5V Operation - Direct LSTTL Input Logic Compatibility, VIL= 0.8V (Max), VIH = 2V (Min) - CMOS Input Compatibility, Il ≤ 1µA at VOL, VOH Pinout CD54HC157, CD54HCT157, CD54HC158, CD54HCT158 (CERDIP) CD74HC157, CD74HCT157, CD74HC158 (PDIP, SOIC) CD74HCT158 (PDIP) TOP VIEW S 1 16 VCC 1I0 2 15 E 1I1 3 14 4I0 1Y 4 13 4I1 2I0 5 12 4Y 2I1 6 11 3I0 2Y 7 10 3I1 GND 8 9 3Y TEMP.

TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
