DG409LAK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG409LAK is a high-performance CMOS analog multiplexer manufactured by Vishay Siliconix. It features a dual 4:1 configuration, providing eight independent channels within a single integrated circuit. The device operates with a supply voltage range of 5 V to 36 V and supports dual supplies up to +/- 15 V. Key electrical specifications include a maximum on-resistance of 29 Ohms, a maximum power dissipation of 900 mW, and a maximum supply current of 500 uA. It utilizes a CDIP-16 package for through-hole mounting and functions reliably across an extended temperature range from -55 C to +125 C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as the specific suffix may indicate lead-containing variants. Check for end-of-life notifications or discontinuation notices prior to procurement planning. Ensure the CDIP-16 package footprint matches the target PCB design constraints.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4:1 multiplexer topology is required for signal routing applications. Consider the wide supply voltage range and extended temperature capabilities for demanding environments. Evaluate the through-hole CDIP-16 package against available surface-mount alternatives if space constraints differ. Compare on-resistance and switching speed requirements against other members of the DG40x family.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG409LAK belongs to the DG40x series of high-performance CMOS analog multiplexers produced by Vishay Siliconix. This series is designed for precision applications requiring low distortion and fast switching. The LAK suffix typically denotes a specific package variant, in this case, the ceramic dual in-line package (CDIP), which offers robust mechanical stability compared to plastic packages.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the specific LAK suffix designation. General family equivalents such as the DG409AJ or DG409EJ may offer similar electrical performance but require verification of package type and lead-free status. Consult official cross-reference lists for confirmed substitutes.
