SN74LS157N – Quadruple 2-Line To 1-Line Data Selectors/Multiplexer IC – DIP-16 Package
The 74LS157; 74LST157 is a high-speed Si-gate CMOS device and is pin-compatible with Low-power Schottky TTL. It is specified in compliance with JEDEC standard no. 7A. The 74HC/HCT157 are quad 2-input multiplexers that 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 a 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.
