Overview
The DG441BDN-T1-E4 is a monolithic quad SPST CMOS analog switch in a 16-pin QFN package. It features a typical on-resistance of 45 Ω and maximum of 80 Ω, with turn-on/turn-off times of 220 ns / 120 ns at ±15 V supplies. Charge injection is -1 pC, off-isolation is -95 dB, and supply current is 1 µA. Operating voltage ranges from ±7 V to ±22 V (dual) or 13 V to 36 V (single). It operates between -40 °C and +85 °C.
Feature Summary
- High-speed switching with low on-resistance for minimal signal distortion
- Minimized charge injection suitable for precision sample-and-hold circuits
- TTL and CMOS compatible logic levels for simple interfacing
- Latchup-proof epitaxial layer construction
Applications
- Data acquisition systems
- Automatic test equipment
- Medical instrumentation
- Communication systems
- Audio switching
Procurement Notes
Verify the specific suffix E4 against the manufacturer's documentation to confirm compliance with RoHS3 standards and material categorization requirements. Ensure the QFN-16 footprint matches the design layout before ordering. Confirm that the single-supply or dual-supply configuration aligns with the target application voltage range.
Selection Notes
Select this component when low on-resistance and fast switching are required for analog signal routing. The QFN-16 package is ideal for space-constrained designs. Verify that the input logic levels meet the TTL/CMOS compatibility thresholds. Consider the power dissipation limits if operating near the upper temperature range.
Part Context
This part belongs to the DG441B series, which serves as an upgraded version of the original DG441. It utilizes Vishay Siliconix's high-voltage silicon-gate process. The device provides four independent SPST switches within a single integrated circuit, designed for high-performance analog signal handling.

FAQ
What is the maximum supply voltage for the DG441BDN-T1-E4?
The absolute maximum rating for the voltage difference between V+ and V- is 44 V.
How does the DG441BDN handle inputs exceeding the supply rails?
Internal diodes clamp signals on Sx, Dx, or INX that exceed V+ or V-. Forward diode current must be limited to the maximum current ratings.
Is the DG441BDN latchup-proof?
Yes, the device is built using an epitaxial layer that prevents latchup.
