STMicroelectronics T74LS158B1 Quad 2-Line to 1-Line Data Selector/Multiplexer

The T74LS158B1 is a high-speed Quad 2-Line to 1-Line Data Selector/Multiplexer designed by STMicroelectronics. This integrated circuit is part of the LS-TTL logic family and is optimized for digital applications. It is commonly used in data routing, signal gating, and multiplexing functions, which are essential in complex digital systems.

This device features four individual 2-line to 1-line multiplexers in a single package, each multiplexer having its own select input. The select input determines which of the two data inputs is routed to the output. With a typical power dissipation of 19 mW and a wide operating voltage range of 4.75V to 5.25V, the T74LS158B1 is a versatile component suitable for a variety of digital logic systems.

The T74LS158B1 offers low power consumption and high noise immunity characteristic of LS-TTL logic. It provides a direct implementation of the truth table of a two-input multiplexer without the need for external gating or inversion. The device is characterized for operation from 0°C to 70°C, making it suitable for commercial-grade applications.
