DG407DN-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG407DN-T1-E3 is a dual 8-channel high-performance CMOS analog multiplexer manufactured by Vishay Siliconix. It selects one of eight differential input pairs to a common differential output using a 4-bit binary address. The device operates with supply voltages ranging from ±5 V to ±20 V or a single 12 V supply, featuring an absolute maximum rating of 44 V. Key electrical parameters include a typical on-resistance of 50 Ω, charge injection of 15 pC, and transition time of 200 ns. It utilizes a 28-pin PLCC package and supports break-before-make switching.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Break-before-make switching action prevents momentary shorting of inputs during channel transitions.
• TTL-compatible control inputs, address lines, and enable functions across the full operating temperature range.
• Epitaxial layer construction prevents latch-up under stress conditions.
• Each channel blocks voltages up to the power supply rails in the off state.

Analog Switches, Multiplexers, Demultiplexers Applications

• High-speed data acquisition systems
• Audio signal switching and routing
• Automated test equipment (ATE) systems
• Avionics applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free termination markings corresponding to the -E3 suffix. Validate that the PLCC-28 package matches design requirements. Check for specific manufacturing lot codes if traceability is required for quality assurance protocols.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when differential signal routing is required within a multiplexed architecture. Ensure the application voltage does not exceed the 44 V absolute maximum rating. Verify that the 28-pin PLCC footprint fits the PCB layout constraints. Consider the 50 Ω on-resistance and 15 pC charge injection limits against signal integrity requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG406/DG407 family of high-performance CMOS analog multiplexers. While the DG406 provides 16 single-ended channels, the DG407 variant specifically offers two independent 8-channel differential configurations. Both share identical pinouts and electrical characteristics optimized for precision instrumentation.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG407DW-T1-E3: Same functional specifications but housed in a 28-pin widebody SOIC package instead of PLCC. Requires footprint modification for surface mount assembly.
