DG211CJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG211CJ is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a monolithic, low-power CMOS design with guaranteed break-before-make switching and operates on dual power supplies ranging from ±4.5V to ±18V. The device does not latch up if power supplies are disconnected while input signals remain connected. Electrical characteristics 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. Supply current is typically 0.4mA, and the component is housed in a 16-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Guaranteed break-before-make switching prevents signal overlap during transitions.
• Nonlatching behavior ensures safe operation when power supplies are turned off with input signals present.
• CMOS and TTL logic compatible inputs simplify interface requirements.
• Elimination of the third VL supply simplifies power distribution compared to original designs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the specific part number matches the required temperature range and package style. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure the ordering suffix aligns with the desired operating conditions and physical form factor for integration into the target system.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG211CJ when break-before-make timing is critical for the application. Compare the 175Ω ON-resistance against circuit requirements to ensure acceptable signal loss. Verify that the ±4.5V to ±18V supply range fits the available power rails. Consider the PDIP-16 package constraints regarding board space and thermal dissipation limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG211CJ belongs to the DG201A/DG211 family of quad SPST CMOS analog switches. It shares the same pinout and general architecture as the DG201ACJ but differs primarily in switching speed specifications. Both devices utilize a low-power CMOS process and offer similar electrical performance characteristics aside from the turn-on and turn-off times.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG201ACJ serves as a direct functional substitute within the same family, offering identical pinouts and lower switching speeds. Other variants such as the DG211DJ provide extended temperature ranges (-40°C to +85°C) while maintaining the same core functionality and package configuration.
