Overview
The DG405BDY-T1-E3 is a low-power, high-speed CMOS analog switch manufactured by Vishay Siliconix. It features four independent SPST switches arranged in two pairs within a 16-pin narrow SOIC package. The device supports single supply voltages from 5 V to 36 V and dual supplies from ±5 V to ±22 V. Key electrical parameters include a maximum on-resistance of 45 Ω at room temperature, rising to 55 Ω across the full operating range. Typical turn-on time is 100 ns with a maximum of 150 ns, while typical turn-off time is 60 ns with a maximum of 100 ns. Leakage current is specified at a maximum of 0.5 nA when off and 1 nA when on at room temperature.
Feature Summary
- Four independent SPST switches configured in two pairs for flexible signal routing
- High-voltage silicon gate process ensures superior on/off performance and break-before-make capability
- Flat on-resistance profile maintained over the full ±15 V analog signal range
- Compatible with TTL and CMOS logic levels for simple interfacing
Applications
- Audio and video switching systems
- Sample-and-hold circuits
- Test equipment signal paths
- PBX and PABX communication networks
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets as manufacturing locations may vary. Ensure proper ESD handling protocols during storage and assembly. Validate package markings against official ordering information to prevent counterfeit substitution.
Selection Notes
Select this component for applications requiring fast switching speeds combined with low power consumption. Suitable for portable and battery-powered designs due to minimal supply current. Verify that the required analog signal range does not exceed the ±15 V limit. Ensure logic input voltage levels align with the specified TTL/CMOS compatibility thresholds.
Part Context
This part belongs to the DG401B/DG403B/DG405B series, which are improved replacements for the legacy DG401/DG403/DG405 models. The 'DG405' designation specifically indicates four SPST switches in two pairs. The '-E3' suffix denotes lead-free terminations using 100% matte tin. The 'T1' suffix indicates tape and reel packaging for automated surface mount assembly.
Replacement Considerations
The DG405BDJ-E3 serves as a DIP-16 replacement variant. Legacy DG405 parts require verification of pinout and parameter compatibility before substitution.
