DG403BDJ-E3

Overview

The DG403BDJ-E3 is a low-power, high-speed CMOS analog switch manufactured by Vishay Siliconix. It features four independent SPST switches in NO/NC combinations within a 16-pin plastic DIP package. The device supports single or dual power supplies ranging from 5 V to 36 V (single) or ±2.5 V to ±22 V (dual). Key electrical parameters include a maximum on-resistance of 45 Ω at room temperature and 55 Ω across the full operating range. Turn-on time is typically 100 ns with a maximum of 150 ns, while turn-off time is typically 60 ns with a maximum of 100 ns. Leakage current is limited to 0.5 nA max at room temperature. The component operates within a temperature range of -40 °C to +85 °C.

Feature Summary

• Provides break-before-make switching action for SPDT configurations
• Compatible with TTL and CMOS logic levels
• Capable of conducting equally well in both directions when on

Applications

• Audio and video switching
• Sample-and-hold circuits
• Test equipment
• PBX and PABX systems

Procurement Notes

Verify the specific suffix 'E3' confirms lead-free matte tin terminations as per Vishay standards. Confirm the 'DJ' suffix corresponds to the 16-pin plastic DIP package. Check the manufacturer's official documentation for the most recent lifecycle status, as availability may vary by region.

Selection Notes

Select this component for applications requiring fast switching speeds and low power consumption. Ensure the supply voltage does not exceed 44 V between V+ and V-. Verify that the analog signal range stays within ±15 V. Consider thermal derating if operating above 75 °C, as power dissipation decreases by 6 mW/°C.

Part Context

This part belongs to the DG401B/DG403B/DG405B series, which are replacements for the popular DG401/DG403/DG405 analog switches. The series utilizes Vishay Siliconix proprietary high-voltage silicon gate process technology to achieve high voltage ratings and superior switch performance.

Replacement Considerations

DG403BDJ is the non-lead-free equivalent.
