Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific datasheet version and environmental compliance status directly with onsemi before procurement. Confirm that the package marking and pinout align with design requirements. Ensure the component meets all relevant RoHS directives applicable to your region. Cross-reference the ordering suffix to confirm the exact packaging type and moisture sensitivity level required for assembly.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single-channel selection from multiple sources is required using standard 5V logic levels. The ACT series offers faster propagation delays compared to older LS variants while maintaining CMOS power efficiency. Verify that the input voltage thresholds are compatible with the driving logic family in the system architecture.
