## Description

The SN74LS257BN is a digital multiplexer IC manufactured by Motorola Semiconductor. This component is designed to multiplex signals from four-bit data sources to four-output data lines in bus-organized systems. It features quadruple 2-line to 1-line data selection with 3-state outputs, which do not load the data lines when the output control pin is at a high logic level.

Key electrical characteristics include its operation within a temperature range of 0°C to 70°C. The device is housed in a 16-pin PDIP package, suitable for through-hole mounting.

This multiplexer is designed for use in high-performance systems requiring bus interface from multiple sources. Its 3-state output capability makes it suitable for applications where data lines need to be selectively driven.
