Overview
The DG333ALDJ-E3 is a precision quad single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It integrates four independently controlled switches in a 20-pin plastic DIP package designed for through-hole mounting. The device operates on single or dual power supplies, supporting voltage ranges from 5 V to 40 V single supply and ±4 V to ±22 V dual supply. Key electrical characteristics include a maximum channel on-resistance of 45 Ω at room temperature, rising to 90 Ω across the full operating temperature range. The component features low input current of 1 μA maximum, turn-on time of 175 ns, and turn-off time of 145 ns. It supports an analog signal range spanning the full supply rails and handles up to 30 mA DC switch current.
Feature Summary
- Four independently controlled SPDT analog switches integrated into a monolithic circuit
- Micro-power operation with supply current less than 1 μA
- Low charge injection performance minimizing measurement errors
- Rail-to-rail analog signal handling capability
Applications
- Audio switching systems
- Test equipment signal routing
- Portable instrumentation
- Communication systems and PBX/PABX
- Switched-capacitor networks
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and shipping format. The -E3 designation indicates lead-free termination compliant with RoHS standards. Confirm that the 20-pin DIP configuration matches the target PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when designing circuits requiring low leakage and precise analog signal routing with minimal power consumption. Ensure the application voltage stays within the specified 5 V to 40 V single supply or ±4 V to ±22 V dual supply limits. Verify that the 45 Ω on-resistance meets the signal integrity requirements for the intended load conditions.
Part Context
This part belongs to the DG333A/DG333AL family of precision analog switches. The 'L' suffix denotes the micro-power variant with significantly lower supply current compared to standard versions. The 'D' indicates the 20-pin wide-body SOIC or DIP package style, while 'J' specifies the plastic DIP option. This series is engineered for high accuracy in data acquisition and signal processing applications.
Replacement Considerations
The DG333ADJ-E3 serves as the non-low-power functional equivalent within the same package. For surface-mount implementations, the DG333ALDW-E3 offers identical electrical specifications in a 20-pin SOIC package.
