74LS157 DIP-16 Quad 2-Input Multiplexer IC (TTL, 5V)

Description -

The 74LS157 DIP is a TTL logic integrated circuit containing four independent 2-input multiplexers in a 16-pin Dual Inline Package (DIP). It belongs to the 74LS Low Power Schottky logic family and is designed for high-speed data selection, bus switching, and digital signal routing.

The device features a common select input and a common active LOW strobe (enable) input that simultaneously control all four multiplexers. When enabled, the select input determines whether the A or B data inputs are routed to the outputs. The 74LS157 is widely used in microprocessor systems, memory interfacing, data routing, and parallel-to-serial conversion.
