PRODUCT DESCRIPTION:

74HC157 Quad 2-Input Multiplexer, conductor, DIP-16

The 74HC/HCT157 are quad 2-input multiplexers which select 4 bits of data from two sources under the control of a common data select input (S). The enable input (E) is  active LOW. When E is HIGH, all of the outputs (1Y to 4Y) are forced LOW regardless of all other input conditions.
 
Moving the data from two groups of registers to four common output buses is a common use of the 74HC/HCT157. The state of the common data select input (S) determines the  particular register from which the data comes. It can also be used as function generator. The device is useful for implementing highly irregular logic by generating any four of the  16 different functions of two variables with one variable common. The 74HC/HCT157 is logic implementation of a 4-pole, 2-position switch, where the position of the switch is determined by the logic levels applied to S.
