Overview
The DG2041DN-T1-E4 is a quad single-pole/single-throw normally-closed analog switch from the Vishay Siliconix DG series. It features a maximum on-resistance of 1.5 Ohms and supports a supply voltage range of 1.8 V to 5.5 V. The device operates with a maximum turn-on time of 42 ns and a turn-off time of 32 ns. It is housed in a QFN-16 package, dissipates up to 1.88 W, and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Quad SPST normally-closed configuration for signal routing
- Low on-resistance of 1.5 Ohms maximum
- Single-supply operation from 1.8 V to 5.5 V
- High-speed switching with 42 ns turn-on time
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal path switching
- Instrumentation and test equipment input selection
- Battery-powered portable devices requiring low power consumption
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to project requirements. Ensure the QFN-16 package footprint matches the design layout. Review datasheet electrical characteristics against system constraints before finalizing procurement decisions.
Selection Notes
Select this component when a normally-closed state is required upon power-up or control signal absence. The low on-resistance suits applications demanding minimal signal attenuation. Single-supply capability simplifies power architecture compared to dual-supply alternatives. Evaluate thermal dissipation limits if operating near maximum current ratings.
Part Context
This part belongs to the DG enhanced analog switch family, characterized by improved leakage limits and lower on-resistance compared to standard CMOS switches. The DG2041 variant specifically provides four independent switches in a compact surface-mount package, suitable for space-constrained designs requiring high performance.
Replacement Considerations
DG2041DN-E4 is listed as an alias part number. Verify pinout compatibility and electrical specifications when substituting. No other cross-model substitutes are confirmed in public documentation.
