Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EPN' against official Analog Devices documentation to confirm lead-free status and RoHS compliance. Confirm that the extended temperature grade matches the required operational environment. Check for obsolescence notices or last-time-buy dates directly from the manufacturer before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual 4:1 high-voltage switching is required in through-hole designs. Ensure the system voltage does not exceed the ±18 V limit. Compare on-resistance and charge injection specifications against alternative switches if signal integrity is critical. Verify package availability as surface-mount alternatives may exist for different form factors.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX389 belongs to the Maxim Integrated high-voltage multiplexer family, designed for applications demanding reliable switching under harsh conditions.
