Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific manufacturer source, as Intersil has been acquired by Renesas Electronics. Confirm RoHS compliance status, as some listings indicate lead-free versions while others may reference older specifications. Ensure the package type matches the required 18-DIP form factor and validate the operating temperature range against application requirements before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8:1 multiplexing function with moderate speed requirements is needed. The 750 Ohm on-resistance suits applications where minimal signal attenuation is critical but high-frequency performance is not the primary constraint. Consider the 18-pin DIP package for prototyping or through-hole designs. Verify that the ±15V supply capability aligns with the system's power distribution network.
