Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix DWR indicates tape-and-reel packaging when ordering. Confirm that the ACT series requires a 5V supply rail, distinct from AC or HC variants. Ensure the SOIC-20 footprint matches the PCB design. Check for RoHS compliance status on the latest datasheet revision before finalizing procurement specifications.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when four independent 2-to-1 multiplexing channels are required with high-speed performance. The ACT series offers faster switching speeds compared to legacy HC devices while maintaining TTL-compatible inputs. Verify that the 20-pin narrow SOIC package fits the available board space and thermal constraints of the application environment.
