Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific manufacturer designation, as components may be listed under Fairchild Semiconductor or ON Semiconductor due to corporate history. Confirm the package type is 16-SOP and ensure compliance with RoHS standards if required for your assembly process. Cross-reference the datasheet version to confirm electrical characteristics match your design requirements.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad 2-to-1 multiplexer with tri-state outputs is required for low-voltage digital applications. Ensure the system operating voltage falls within the 2V to 3.6V range. Consider the 16-SOP package constraints for PCB layout and thermal management during integration.

Signal Switches, Multiplexers, Decoders Part Context

This part is part of the 74LCX family, designed for low-voltage CMOS applications. It serves as a digital selector, allowing data from two sources to be routed to a single output based on a select input. The 3-STATE feature enables bus sharing in complex digital systems.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for equivalents such as the 74LS257 for higher voltage compatibility, though logic levels differ. Verify pinout compatibility with other LCX series multiplexers before substitution.
