Overview
The DG418BDQ-T1-E3 is a precision monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It operates within a ±15 V dual supply or up to 36 V single supply, providing an analog signal range of ±15 V. The device features a maximum on-resistance of 25 Ω and supports a continuous current of 30 mA. Switching performance includes a turn-on time of 89 ns and a turn-off time of 80 ns at room temperature. It utilizes a TSSOP-16 package configuration in this specific variant, though the datasheet lists SOIC-8 and MSOP-8 for the series. The component operates across a temperature range of -40 °C to +85 °C.
Feature Summary
- High-voltage silicon gate (HVSG) process construction ensures superior switching performance and prevents latchup via an epitaxial layer.
- Bidirectional conduction capability allows equal signal flow in both directions when on, while blocking up to the power supply level when off.
- TTL and CMOS compatible logic control simplifies interfacing with standard digital systems.
Applications
- Precision test equipment
- Battery powered industrial and military systems
- Sample-and-hold circuits
Procurement Notes
Verify the exact package type against the ordering suffix, as the datasheet specifies SOIC-8 and MSOP-8 for the DG418B series. Confirm RoHS compliance status through official documentation. Validate that the intended operating voltage does not exceed the absolute maximum ratings to ensure device reliability.
Selection Notes
Select this component for applications requiring high-performance analog signal switching with low power consumption. Ensure the design accommodates the specified on-resistance and leakage currents. Verify that the board space constraints align with the available package options listed in the manufacturer's ordering information.
Part Context
This part belongs to the DG417B/DG418B/DG419B family of precision monolithic quad SPST CMOS analog switches. The DG418B specifically responds to opposite control logic levels compared to the DG417B. The series is designed for portable and battery-powered applications requiring efficient use of board space.
Replacement Considerations
DG417BDQ-T1-E3: Compatible alternative with inverted logic control. DG419BDQ-T1-E3: Alternative offering SPDT configuration with break-before-make switching action. Both share similar electrical characteristics and package options.
