DG441DJ+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG441DJ+ is a quad, single-pole/single-throw (SPST) analog switch featuring four normally closed channels in a 16-pin Plastic DIP package. It operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. Key electrical parameters include an on-resistance of 85Ω maximum, on-resistance matching of 4Ω maximum, and on-resistance flatness of 9Ω maximum. Switching times are less than 250ns for turn-on and 170ns for turn-off. The device guarantees low charge injection of 10pC maximum and off-leakage current below 5nA at +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component designation includes the plus suffix to confirm lead-free compliance. Ensure the ordering code matches the specific temperature grade required for the application environment. Confirm the package type corresponds to the intended board layout constraints before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when normally closed SPST switching is required within a quad configuration. Verify that the bipolar supply voltage range meets the system requirements for optimal on-resistance performance. Consider the thermal dissipation limits if operating near the upper temperature boundaries.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the redesigned DG441/DG442 series of analog switches. It serves as a direct upgrade for industry-standard legacy parts while offering improved electrical characteristics such as lower charge injection and better channel matching compared to previous generations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG442DJ+ is the electrically similar counterpart featuring normally open switches instead of normally closed ones. Both share identical pinouts and electrical specifications except for the default switch state.
