Product Overview
The SN74LS157N is a type of digital integrated circuit (IC) that is commonly used as a multiplexer or data selector.
A multiplexer is a device that allows multiple input signals to be selectively connected to a single output signal. The SN74LS157N is a quad 2-input multiplexer, which means it has four independent 2-input multiplexers in a single package.
Each 2-input multiplexer has two data inputs, a select input, and an output. The select input controls which of the two data inputs is connected to the output. When the select input is high, the first data input is connected to the output. When the select input is low, the second data input is connected to the output.
The SN74LS157N is designed to operate with logic levels that are compatible with TTL (transistor-transistor logic) circuits.
