74HC157 Quad 2-Input Multiplexer IC (DIP-16 Package)

74HC157 Quad 2-Input Multiplexer IC is a high-performance CMOS logic device designed for efficient digital data selection and signal routing. It integrates four independent 2-to-1 multiplexers in a single package, allowing designers to select between two sets of data inputs using a common select line. With low power consumption, high noise immunity, and fast switching speeds, the 74HC157 is an ideal choice for modern digital and embedded system applications.

This IC belongs to the 74HC (High-Speed CMOS) logic family, offering full compatibility with TTL logic levels while delivering superior power efficiency compared to traditional TTL devices. The presence of a common active-LOW enable (strobe) input allows all outputs to be disabled simultaneously, making it suitable for bus-oriented architectures and data multiplexing tasks.
