DG509ACY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG509ACY is a CMOS monolithic analog multiplexer manufactured by Intersil. It features an 8-channel configuration with dual 4-channel architecture, allowing flexible signal routing in data acquisition and communication systems. The device operates with TTL and CMOS-compatible address and enable inputs, ensuring broad compatibility with standard logic families. It supports a maximum power supply rating of 44V and incorporates break-before-make switching to prevent signal overlap during channel transitions. High latch-up immunity ensures reliable operation in noisy environments.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer source carefully, as Intersil was acquired by Renesas Technology. Ensure the component meets current automotive or industrial qualification standards if required for your specific application. Check for RoHS compliance status on the specific batch. Confirm package availability and lead times through authorized distributors.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel analog switch with dual independent sections is required. It is suitable for applications needing high voltage tolerance up to 44V and robust noise immunity. Consider alternatives if lower on-resistance or different pin counts are needed. Verify that the CMOS input levels match your system's logic voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG509A belongs to a family of CMOS analog multiplexers that includes the DG506A, DG507A, and DG508A. These devices share similar architectural features but differ in channel count and configuration. The DG509A specifically offers an 8-channel/dual 4-channel layout, distinguishing it from the 16-channel DG506A and other variants in the series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the DG508A and DG506A from Intersil or Renesas. Cross-manufacturer equivalents may be available from Maxim Integrated or Texas Instruments, provided pinouts and electrical characteristics align. Verify functional compatibility before replacement.
