MAX368EPN

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX368EPN is a fault-protected analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features an 8:1 single-channel configuration housed in an 18-pin PDIP package for through-hole mounting. The device operates on dual supplies ranging from ±4.5 V to ±18 V, with a typical operating voltage of 15 V. Key electrical parameters include a maximum on-resistance of 1.8 kOhms, a maximum power supply current of 2 mA, and a charge injection of 55 pC. Switching performance specifies a maximum turn-on time of 1.5 µs and a turn-off time of 1 µs, resulting in a propagation delay of 1000 ns. The component supports an industrial temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized channels as the part is marked obsolete. Confirm RoHS compliance status, as datasheets indicate potential non-compliance for specific manufacturing batches. Validate package integrity upon receipt to ensure pin alignment matches the 18-PDIP specification before integration into PCB designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-voltage fault tolerance and data latching are required for analog signal routing. Ensure the application utilizes dual power supplies within the ±4.5 V to ±18 V range. Consider the 1.8 kOhm on-resistance limit for signal integrity requirements and verify that the 1.5 µs switching speed meets system timing constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX368 series of analog multiplexers. It shares functional similarities with the MAX369 but differs in specific pinout or feature sets. The device represents Maxim Integrated's legacy solution for robust analog switching applications prior to the discontinuation of this specific through-hole package variant.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is obsolete, engineers must evaluate alternative multiplexers with compatible voltage ratings and package footprints, potentially requiring schematic and layout modifications.
