DG417AK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG417AK is a single-channel, monolithic CMOS analog switch manufactured by Vishay Siliconix. It features a SPST configuration housed in an 8-pin MiniDIP (CDIP-8) package. The device operates with dual power supplies ranging from ±15 V to ±36 V or a single supply up to 36 V. Key electrical parameters include a maximum on-resistance of 35 Ohms, a maximum power dissipation of 600 mW, and a maximum supply current of 1 uA. Switching times are specified at 175 ns for turn-on and 145 ns for turn-off. The component supports a continuous DC switch current of 30 mA and functions within a temperature range of -55°C to +125°C.

• Industrial process control systems requiring wide temperature tolerance
• Test and measurement equipment precision switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix AK against official Vishay documentation to confirm the CDIP-8 package and military grade classification. Check for active production status as legacy parts may be subject to discontinuation notices. Ensure compliance with RoHS directives if required by the end application, noting that older military variants may have different environmental certifications than standard commercial equivalents.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when hermetic sealing and extended temperature stability are critical requirements. Compare the 35 Ohm on-resistance against lower-resistance alternatives if signal integrity at high currents is a priority. Verify that the 600 mW power dissipation rating accommodates the thermal design of the target enclosure without excessive heat sinking.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG41x series of precision analog switches. It shares functional similarities with the DG417BDY and DG417DJ but differs in package type and operating temperature range. The AK suffix typically denotes the ceramic DIP variant, distinguishing it from plastic SOIC or MSOP versions within the same family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include other DG417 variants in CDIP-8 packages such as the DG417AK-E3. For non-hermetic applications, verify if plastic DIP equivalents meet the thermal and mechanical requirements of the system.
