40257F

Overview

The IDT 40257F is a quad 2-to-1-line data selector manufactured by Integrated Device Technology Inc. It functions as a multiplexer, routing one of two input lines to a single output based on control signals. The device is part of the standard logic family and is designed for signal switching applications.

Feature Summary

• Provides four independent 2-input multiplexing channels within a single package
• Routes selected input data to corresponding outputs via control logic

Applications

• Data selection in digital logic circuits
• Signal routing in communication systems
• Input multiplexing for microcontroller interfaces

Procurement Notes

Verify the manufacturer designation, as IDT has been acquired by Renesas Electronics. Confirm that the component corresponds to the original IDT specifications rather than generic equivalents. Ensure the datasheet matches the specific functional requirements for the quad 2-to-1 line selector configuration before procurement.

Selection Notes

Select this component when a compact solution for multiple parallel data paths is required. It serves as a direct replacement for other quad multiplexers in the same logic family. Verify pin compatibility and voltage levels against existing system designs to ensure seamless integration without circuit modification.

Part Context

This component belongs to the category of signal switches, multiplexers, and decoders. It is classified under integrated circuits for logic applications. The device is widely used in digital electronics for managing data flow between different circuit blocks efficiently.

Replacement Considerations

Compatible substitutes include CD40257BDMSH from Renesas and Harris. These parts share the quad 2-to-1 multiplexer functionality and are documented as equivalent alternatives in technical databases.
