The SN74LS257BMEL is an Integrated Circuit (IC) component that belongs to the SN74LS series manufactured by Texas Instruments. It is a quad 2-line to 1-line data selector/multiplexer with 3-State outputs, and it is designed to be used in various digital applications.
Here are the key features of the SN74LS257BMEL:
1. Quad 2-line to 1-line data selector/multiplexer: The IC has four independent data selectors/multiplexers within a single chip. Each selector/multiplexer allows you to choose between two input lines and route the selected data to a single output line.
2. 3-State outputs: The IC has 3-State outputs, which means the output lines can be in one of three states: high logic level, low logic level, or high impedance. The 3-State outputs offer flexibility in connecting multiple ICs together and avoiding data contention.
3. Separate output enable (OE) for each selector/multiplexer: The IC provides an individual output enable input for each selector/multiplexer, allowing you to selectively enable or disable the output of each selector independently.
4. Low power consumption: The SN74LS257BMEL is designed to operate with low power consumption, making it suitable for battery-powered or energy-efficient electronic devices.
5. Wide operating voltage range: The IC can operate within a wide range of supply voltages, typically between 4.75V and 5
