Overview
The DG1411EEQ-T1-GE4 is a monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It features a typical on-resistance of 1.5 Ω and operates from a single supply of 4.5 V to 24 V or dual supplies of ±4.5 V to ±15 V. The device supports rail-to-rail signal handling, offers a -3 dB bandwidth of 150 MHz, and includes break-before-make switching. Packaged in a TSSOP-16 format, it provides low charge injection and high off-isolation for precision signal routing.
Feature Summary
- Normally closed SPST configuration with integrated logic supply
- Low on-resistance flatness ensuring excellent linearity
- Rail-to-rail analog signal handling capability
- Break-before-make switching operation
Applications
- Medical and healthcare equipment
- Data acquisition systems
- Industrial control and automation
- Test and measurement equipment
- Audio and video signal switching
Procurement Notes
Verify the specific package variant against project requirements, as the DG1411E series is available in both TSSOP-16 and QFN-16 configurations. Confirm that the normally closed logic sense aligns with the system design before finalizing orders. Ensure compliance with RoHS standards and check for any recent product change notices regarding manufacturing locations.
Selection Notes
Select this component when a normally closed state is required at logic zero inputs. Compare against DG1412E for normally open applications or DG1413E for mixed configurations. Verify that the 1.5 Ω on-resistance meets the insertion loss requirements of the target circuit. Ensure the operating temperature range of -40 °C to +125 °C covers the environmental conditions.
Part Context
This part belongs to the DG1411E family of precision analog switches. It shares the same core electrical specifications and CMOS process technology as the DG1412E and DG1413E models. The primary distinction lies in the switch logic polarity and the physical package type, which determines the pinout compatibility and thermal characteristics within the broader Vishay Siliconix portfolio.
Replacement Considerations
DG1412EEQ-T1-GE4: Identical electrical performance but features normally open switches instead of normally closed.
FAQ
Does the DG1411EEQ-T1-GE4 require a separate VL logic supply?
No, the device does not require a separate VL logic supply; all digital inputs have defined thresholds compatible with standard TTL/CMOS logic levels.
What is the maximum continuous current rating for the TSSOP-16 package?
The maximum continuous switch current is 190 mA at an ambient temperature of 25 °C.
How does the break-before-make time affect switching performance?
The device guarantees a minimum break-before-make time of 10 ns at ±15 V supply, preventing simultaneous conduction between channels during state transitions.
