DG411DJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411DJ is a monolithic CMOS analog switch manufactured by Vishay / Siliconix. It features four independent single-pole single-throw (SPST) channels in a PDIP-16 through-hole package. The device operates on dual supplies ranging from ±5 V to ±20 V, with a maximum voltage range of 44 V. Key electrical parameters include a maximum on-resistance of 35 Ohms, a maximum turn-on time of 175 ns, and a maximum turn-off time of 145 ns. It supports a continuous DC switch current of 30 mA and has a maximum power dissipation of 470 mW. The component functions within an operating temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Four independent SPST analog switches with TTL and CMOS compatible digital inputs
• Low charge injection design simplifies sample and hold applications
• Epitaxial layer prevents latch-up associated with older CMOS technologies
• Bilateral switches equally matched for AC or bidirectional signals

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer origin carefully, as the DG411 part number is produced by multiple vendors including Renesas and Vishay. Confirm that the specific suffix 'DJ' corresponds to the Vishay / Siliconix PDIP-16 variant rather than the Renesas SOIC or TSSOP versions. Ensure the RoHS status matches project requirements, as some listings indicate non-compliance for this specific manufacturer's version.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG411DJ when a through-hole DIP package is required for prototyping or legacy board designs. This specific variant offers a maximum on-resistance of 35 Ohms and operates on dual supplies up to ±20 V. Compare against the DG411DYZ-T if surface-mount assembly is preferred, noting the difference in package type and potential supply chain availability between the Vishay and Renesas manufacturing sources.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG411 series serves as a drop-in replacement for the popular DG211 and DG212 series devices. Manufactured using a high-voltage silicon-gate process, it provides lower analog on-resistance and faster switching times compared to its predecessors. The series includes four bilateral switches that are well-suited for controlling signals up to 40 V peak-to-peak.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitute part numbers include DG411DYZ and DG411DVZ-T from Renesas / Intersil. These alternatives offer identical functional specifications but utilize different packages such as SOIC-Narrow-16 or TSSOP-16.
