Overview
The DG409DY-T is a dual differential analog multiplexer switch IC manufactured by Renesas Electronics Corporation. It features two independent 4:1 multiplexing channels housed in a 16-pin SOIC-Narrow surface-mount package. The device supports single supply voltages ranging from 5 V to 36 V and dual supplies from ±5 V to ±20 V. Key electrical specifications include a maximum on-resistance of 100 Ohms, a typical charge injection of 20 pC, and a maximum leakage current of 500 pA. Switching performance is characterized by a maximum turn-on time of 180 ns and a turn-off time of 120 ns, with a propagation delay of 250 ns. The component operates within an industrial temperature range of -40°C to +85°C.

Procurement Notes
Verify the manufacturer designation carefully, as the DG409 series has been produced by multiple entities including Intersil, Vishay, and Renesas. Confirm that the specific suffix matches the required packaging format and compliance standards. Ensure the source document explicitly identifies Renesas Electronics Corporation as the producer to avoid confusion with equivalent parts from other manufacturers.
Selection Notes
Select this component when a dual 4:1 multiplexer with differential capability is required. Verify that the 100 Ohm on-resistance and 500 pA leakage current meet the system's signal integrity requirements. Ensure the supply voltage range aligns with the available power rails. Consider the 16-SOIC package dimensions for PCB layout constraints and thermal management needs.
Part Context
The DG409 belongs to the DG4xx family of CMOS analog multiplexers. This series is designed for general-purpose signal switching applications. The device integrates control logic and analog switches on a single chip. It is commonly used in instrumentation and communication systems where reliable signal routing is essential.
Replacement Considerations
Publicly confirmed substitute part numbers are not provided in the verified documentation. Cross-referencing with other manufacturers requires careful verification of pin compatibility and electrical parameters.
