74HC157 is a 16-Pin Quad 2-Input Multiplexer IC having a 2V to 6V Operating Voltage range with 1uA Low Input current and high noise immunity. It selects 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.
