Overview
The DG419BDJ-E3 is a precision monolithic CMOS analog switch manufactured by Vishay Siliconix. It features a single SPDT configuration housed in an 8-pin Plastic MiniDIP package. The device operates with dual supply voltages ranging from ±15 V to ±20 V, or a single supply up to 36 V. Key electrical parameters include a maximum on-resistance of 25 Ω at room temperature and 29 Ω across the full operating range. Turn-on time is specified at a maximum of 89 ns, while turn-off time reaches 80 ns under standard test conditions. The component supports a continuous current of 30 mA and maintains low power consumption with a maximum supply current of 1 µA.
Feature Summary
- Break-before-make switching action ensures reliable signal routing without shorting paths.
- High-voltage silicon gate process provides superior switching performance and latchup protection.
- TTL and CMOS compatible logic levels simplify digital control interfacing.
Applications
- Precision test equipment
- Battery powered systems
- Sample-and-hold circuits
Procurement Notes
Verify the specific suffix 'E3' confirms RoHS compliance when sourcing replacements. Confirm the 'DJ' designation matches the required through-hole PDIP-8 footprint for your PCB layout. Check the manufacturer's discontinuation notices as availability may be limited for legacy packages.
Selection Notes
Select this part for applications requiring a single SPDT switch with high voltage tolerance. Ensure the board space accommodates the 8-pin DIP package rather than surface-mount alternatives like SOIC-8. Validate that the 25 Ω on-resistance meets the signal integrity requirements of your specific circuit design.
Part Context
This component belongs to the DG417B/DG418B/DG419B series of precision analog switches. While the DG417B and DG418B offer SPST configurations, the DG419B specifically provides the SPDT topology. The series utilizes Vishay's high-voltage silicon gate process for robust operation in industrial environments.
