Features  
Description  
• Common Select Inputs  
• Separate Enable Inputs  
• Buffered inputs and Outputs  
• Fanout (Over Temperature Range)  
The ’HC157, ’HCT157, ’HC158, and ’HCT158 are quad 2-  
input 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

• Wide Operating Temperature Range . . . -55 C to 125 C 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.
