74HC157D

The 74HC157D is a high-speed CMOS quad 2-to-1 multiplexer. It is part of the 74HC series, which is compatible with TTL (Transistor-Transistor Logic) levels. The device features low power consumption, high noise immunity, and can operate at a wide voltage range, typically from 2V to 6V.
Each multiplexer in the 74HC157D has two data inputs (A and B), a select input (S), and an output (Y). The select input determines which of the data inputs is transmitted to the output. When the select input is low, data input A is selected, and when high, data input B is selected. Additionally, the device includes a common active-low enable input (E\*), which, when high, forces all outputs to low regardless of the select or data inputs.
The 74HC157D is commonly used in digital circuits for data routing, signal switching, and implementing logic functions. It is available in various package types, such as SO-16 and TSSOP-16, making it suitable for a variety of applications in consumer electronics, telecommunications, and industrial systems.

The 74HC157D is a high-speed CMOS quad 2-to-1 multiplexer/demultiplexer.
