DG409DY+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG409DY+ is a CMOS analog multiplexer switch IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features two independent SP4T (Single Pole, Four Throw) switches within a 16-pin SOIC package. The device operates on single supplies from 5V to 30V or dual supplies from ±5V to ±20V. Key electrical parameters include a maximum on-resistance of 175 Ohms and a channel-to-channel matching of 1.5 Ohms. Switching times are specified with a maximum turn-on time of 600 ns and turn-off time of 300 ns. The component supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify authenticity through authorized distributors as counterfeit components exist in the market. Confirm RoHS compliance status via official datasheets before integration. Check current supply chain availability due to potential allocation constraints. Ensure packaging integrity matches required handling specifications for surface mount assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual four-channel switching is required within a compact SOIC footprint. Compare on-resistance values against system voltage drop requirements. Verify logic level compatibility with driving microcontrollers. Consider thermal dissipation limits based on total power consumption calculations for enclosed environments.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG408/DG409 series of improved CMOS analog switches. It serves as a functional upgrade over earlier generations with enhanced switching speed and lower charge injection characteristics. The device complements other members like the DG401 and DG403 which offer different channel configurations such as SPST or SPDT arrangements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible alternatives may include the DG409 without the plus suffix for legacy non-RoHS applications. Cross-reference with DG408 variants if single-pole eight-throw configuration is acceptable. Verify electrical parameter overlaps before substituting with generic CMOS multiplexers.
