74LS258 Quad 2 To 1 Data Selectors/Multiplexers IC With 3-State Outputs

The 74LS258 Multiplexer IC is designed to multiplex signals from four-bit data sources to four-output data lines in bus-organized systems. The IC is designed to operate over a temperature range of 0 to 70°C. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers. The IC also constitutes a wide array of features such as thermal overload protection & ESD protection. The IC 74LS258 is smaller in size and it has a much faster speed which makes it reliable in every kind of device.

What is a Multiplexer/Data selector?

A multiplexer/data selector is a digital combinational logic circuit that toggles one of several input lines to a single common output line. The select lines determine which input is connected to the output, and also to increase the amount of data that can be sent over a network within a certain time. It is also called a data selector.
