DG409AK/883B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG409AK/883B is an improved CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features a CDIP-16 ceramic dual in-line package designed for high-reliability applications. The device integrates eight independent switches, configurable as either a single 8:1 multiplexer or two separate 4:1 multiplexers. It operates with a single supply voltage ranging from 5 V to 30 V, or dual supplies up to ±20 V. Key electrical specifications include a maximum on-resistance of 175 Ohms, a propagation delay of 600 ns, and an off-isolation of -85 dB at 1 MHz. The component supports a wide operating temperature range from -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the authenticity of the /883B suffix, which indicates military-grade qualification. Confirm the package type is CDIP-16 ceramic rather than plastic variants. Check for lot traceability documentation required for defense contracts. Ensure the supplier provides original manufacturer testing data. Validate that the component meets specific MIL-STD requirements if applicable.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when high reliability and radiation hardness are critical. Compare against plastic DG409DY+ for cost-sensitive commercial designs. Consider the higher on-resistance compared to lower-voltage CMOS switches. Evaluate thermal dissipation capabilities within the ceramic package constraints. Verify voltage headroom matches the system's single or dual supply rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG409 series of improved CMOS analog multiplexers. The /883B suffix denotes compliance with MIL-PRF-38534 standards for hybrid microcircuits. It serves as a ruggedized alternative to standard commercial grade switching ICs. The series is widely used in aerospace and defense electronics where long-term stability is mandatory.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG409AK/883B is functionally equivalent to other DG409 variants with military qualification. Plastic packages like DG409DY+ offer similar electrical performance but lack hermetic sealing. Cross-reference with DG408 for 4-channel only configurations. Verify pin compatibility before substituting with non-hermetic versions.
