DG409DJZ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG409DJZ is a dual 4-channel differential multiplexer manufactured by Renesas Electronics Corporation, originally developed under the Intersil brand. It utilizes CMOS technology and is housed in a 16-pin Plastic Dual In-Line Package (PDIP-16). The device features two independent 4:1 multiplexers with differential inputs. Key electrical parameters include a maximum on-resistance of 100 Ohms, a maximum turn-on time of 180 ns, and a maximum turn-off time of 120 ns. It operates within a supply voltage range of 5 V to 34 V single-ended or ±5 V to ±20 V split supplies. The component supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer origin, as the DG409 series was historically produced by Harris, Intersil, Maxim, and Vishay before being acquired by Renesas. Confirm that the 'Z' suffix indicates RoHS compliance and lead-free status according to the specific datasheet revision. Ensure the package type matches the required PDIP-16 footprint and validate the operating temperature grade against system requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-channel differential multiplexer is required for analog signal routing. Compare on-resistance and leakage specifications against alternative CMOS multiplexers if signal integrity is critical. Verify that the input logic levels are compatible with the controlling microcontroller or FPGA. Consider the PDIP-16 package constraints for PCB layout and thermal management in dense assemblies.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG409 is part of the broader DG4xx series of CMOS analog multiplexers. This series includes variants such as the DG409DZ (SOIC package) and DG409EJ (industrial grade). The device serves as a drop-in replacement for older discrete multiplexer solutions, offering integrated control logic and improved switching speeds compared to earlier generations like the DG211/DG212 series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers include DG409DYZ-T and DG409DZ. These alternatives offer identical functional specifications but may differ in package style (e.g., SOIC-Narrow-16 vs. PDIP-16). Verify pinout compatibility and package dimensions before substitution.
