DG212DJ+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG212DJ+ is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on dual power supplies ranging from ±4.5V to ±18V and features inverted control inputs. The device guarantees break-before-make switching and maintains an essentially constant on-resistance over the analog signal range. Electrical specifications at ±15V include a maximum drain-source on-resistance of 175Ω, a maximum turn-on time of 1000ns, and a maximum turn-off time of 500ns. It supports continuous currents up to 20mA and requires no third logic supply voltage.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Guaranteed nonlatching operation when power supplies are disconnected with input signals present
• CMOS and TTL logic compatible without requiring a separate logic supply voltage
• Monolithic low-power CMOS design suitable for portable applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the ordering suffix corresponds to the specified plastic DIP package and temperature range. Request original datasheets and RoHS compliance documentation prior to purchase to ensure alignment with project requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring quad SPST switching with inverted logic control. Ensure the application utilizes dual power supplies within the ±4.5V to ±18V operational range. Verify that the required on-resistance and leakage current specifications align with the guaranteed electrical characteristics provided in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG202/DG212 family of quad SPST CMOS analog switches. The DG212 variant is distinguished by its inverted control inputs compared to the DG202. Both devices share similar electrical performance but differ in logic interface polarity. The series is designed for general-purpose analog signal routing in mixed-signal environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG202DJ+ serves as a functional alternative within the same family, differing only in control input polarity. Other pin-compatible options may exist within the broader Maxim Integrated portfolio, though specific parameters should be cross-referenced against the original design requirements.
