DG411AK/883B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411AK/883B is a high-reliability quad single-pole single-throw (SPST) normally-closed analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It utilizes CMOS technology and features a ceramic dual in-line package (CDIP-16). The device supports a single supply voltage range of 10V to 30V or dual supplies of ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 45 Ohms, a channel-to-channel matching of 3 Ohms maximum, and a charge injection of 5pC. Switching times are specified with a maximum turn-on time of 175ns and a maximum turn-off time of 145ns. The component operates within a temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify authenticity through authorized distributors due to the presence of military-grade variants. Confirm that the /883B suffix indicates compliance with MIL-PRF-38534 standards. Check for lot traceability documentation required for defense contracts. Ensure the CDIP-16 package matches the target PCB footprint. Validate operating temperature ranges against specific environmental requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally-closed configuration is required for safety or fail-safe operation. Compare on-resistance specifications against other DG411 variants if lower resistance is needed. Consider the thermal dissipation capabilities of the ceramic package for high-power applications. Verify compatibility with TTL or CMOS logic levels for control signals. Evaluate the need for hermetic sealing versus standard plastic packages based on environmental exposure.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG411 series of precision monolithic quad SPST CMOS analog switches. The /883B suffix denotes a military-grade version compliant with MIL-PRF-38534, offering enhanced reliability compared to commercial variants. It is functionally similar to the DG411DJ+ but differs in packaging and qualification standards. The series is designed for applications requiring low distortion and fast switching speeds.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG411DJ+ offers similar electrical characteristics in a plastic DIP package but lacks military qualification. DG411AK provides the same functionality in a ceramic package but may differ in specific reliability testing criteria. Verify pinout compatibility before substitution. Check if the replacement meets the required radiation hardness or thermal performance standards.
