DG409EUE

Analog Switches, Multiplexers, Demultiplexers Overview

The DG409EUE+ is a dual 4-channel CMOS analog multiplexer/demultiplexer in a 16-pin TSSOP package. It operates with single supplies from +5V to +30V or dual supplies from ±5V to ±20V. Key electrical parameters include a maximum on-resistance of 175Ω, an on-resistance matching of 8Ω max, and flatness of 9Ω max. The device features low charge injection (15pC max) and input leakage current under 5nA at +85°C. Digital inputs are TTL/CMOS compatible, and ESD protection exceeds 2000V per MIL-STD-883 Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EUE+' against official documentation to confirm the -40°C to +85°C temperature range and TSSOP-16 packaging configuration. Ensure compatibility with existing board layouts as this component serves as a direct pin-compatible replacement for legacy designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual 4-channel switching is required within a compact surface-mount footprint. Consider the 175Ω on-resistance limit and ±20V dual supply capability during circuit design. Verify that the digital control logic aligns with the specified TTL/CMOS voltage thresholds for reliable operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG408/DG409 series of improved CMOS analog multiplexers manufactured by Analog Devices / Maxim Integrated. The series is designed to replace older industry-standard versions while maintaining identical pinouts. The DG409 specifically provides two independent 4-channel multiplexing paths.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG409EUE is a direct pin-compatible replacement for the legacy DG409. The ADG409 offers enhanced LC2MOS performance but requires verification of pinout compatibility if used as a substitute.
