SN74HC157DR

The SN74HC157DR is a high-speed CMOS quad 2-to-1 line data selector/multiplexer. It is part of Texas Instruments' 74HC series of logic devices. This component features four independent 2-input multiplexers with common select and enable inputs. It operates on a wide voltage range from 2V to 6V, making it versatile for various applications.
The SN74HC157DR selects data lines based on the state of the select input (S): when S is low, the multiplexer outputs the data present at the A inputs, and when S is high, it outputs the data present at the B inputs. The enable input (E) is active-low, meaning the device is enabled when E is low. This multiplexer also features low power consumption and high noise immunity, typical of CMOS devices.
The device comes in a small-outline integrated circuit (SOIC) package, making it suitable for space-constrained applications. It is widely used in digital circuits for data routing, switching, and signal multiplexing, offering a simple solution for combining multiple data sources into a single output stream.
