Description  
• Common Select Inputs  
• Separate Enable Inputs  
• Buffered inputs and Outputs  
• Fanout (Over Temperature Range)  
The Harris CD74HC157, CD74HCT157, CD74HC158 and  
CD74HCT158 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-

• Wide Operating Temperature Range . . . -55 C to 125 C Moving data from two groups of registers to four common  
output busses 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.
