Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the RE4 suffix indicates lead-free and RoHS compliance status against current manufacturer documentation. Confirm the TSSOP-20 package outline matches your PCB footprint requirements. Ensure the operating voltage and temperature ranges align with your system specifications before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when multiple independent signal paths require simultaneous selection with minimal propagation delay. The AC logic series offers faster performance compared to standard HC devices while maintaining compatible pinouts. Verify that the 20-pin TSSOP package fits your assembly constraints and thermal management needs.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AC11257 family of high-speed CMOS multiplexers. It serves as a functional equivalent to other quad 2-to-1 selectors but provides specific three-state output control. The device is designed for applications requiring efficient data path management in complex digital architectures.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74AC11257DW is a verified alternative offering identical logical functionality in a SOIC-20 package. Verify pin compatibility and thermal characteristics when substituting between TSSOP and SOIC packages.
