DG407BDN-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG407BDN-E3 is a CMOS analog multiplexer manufactured by Vishay Siliconix, housed in a PLCC-28 surface-mount package. It functions as an 8-channel single-ended to differential multiplexer with a 1-of-8 configuration. The device supports dual supply voltages ranging from ±5 V to ±20 V and operates within a temperature range of -40 °C to +85 °C. Key electrical specifications include a maximum on-resistance of 120 Ohms, a maximum break time of 300 ns, and a maximum make time of 600 ns. It dissipates up to 450 mW and draws a maximum supply current of 500 uA.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching action prevents input shorting during channel transitions.
• TTL-compatible control inputs, address lines, and enable signals across the operating temperature range.
• High voltage tolerance allows operation with power supplies up to ±20 V or 44 V single supply.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring signal routing
• Audio signal switching and routing networks
• Automated test equipment (ATE) signal paths
• Avionics instrumentation interfaces

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead times prior to integration. Check for end-of-life notifications as availability may be restricted. Ensure storage conditions meet moisture sensitivity level requirements for PLCC packages.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexing function with differential output capability is required. Compare on-resistance and break-before-make timing against system signal integrity needs. Verify that the PLCC-28 footprint aligns with the PCB layout constraints. Consider thermal dissipation limits if multiple units are active simultaneously.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG406/DG407 series of high-performance CMOS analog multiplexers. It shares architectural similarities with the DG406 but offers differential output configuration. The series utilizes a 44V silicon gate CMOS process designed for low power consumption and high reliability in industrial and aerospace environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-to-pin replacements should be verified against the official datasheet. Alternative parts must match the 8:1 multiplexer configuration, PLCC-28 package, and ±20 V supply range. Check for equivalent on-resistance and switching speed specifications to ensure circuit compatibility.
