DG441MY/PR+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG441MY/PR+ is a quad, single-pole/single-throw (SPST) analog switch from the redesigned DG441/DG442 series. It features four normally closed switches with an on-resistance of 85 Ω max and guaranteed on-resistance flatness over the signal range at 9 Ω max. The device operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. Switching times are less than 250ns for tON and less than 170ns for tOFF. It offers low charge injection of 10pC max and withstands electrostatic discharge of 2000V min per Method 3015.7. This specific variant supports an extended temperature range of -55°C to +125°C and is housed in a 16-pin Narrow SO package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix MY/PR+ corresponds to the specified narrow SOIC package and the -55°C to +125°C military-grade temperature range. Confirm lead-free status (+ symbol) matches project requirements. Ensure compatibility with existing PCB footprints for the 16-pin narrow SO form factor before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high reliability across extreme temperatures (-55°C to +125°C) is required. The narrow SO package suits space-constrained designs needing through-hole or surface-mount flexibility. Consider the 85 Ω max on-resistance and 10pC charge injection limits for precision signal routing applications where low distortion is critical.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG441/DG442 family of improved quad SPST analog switches. The DG441 variant specifically provides four normally closed switches, distinguishing it from the DG442 which offers normally open configurations. Both share identical electrical characteristics and pinouts, allowing for functional interchangeability based on the desired default switch state.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum voltage rating for the V+ pin?

The absolute maximum rating for the V+ pin referenced to V- is 44V.

How does the DG441 differ from the DG442?

The DG441 contains four normally closed (NC) switches, whereas the DG442 contains four normally open (NO) switches.

Is the exposed pad used in the Thin QFN package connected internally?

Yes, the exposed pad (EP) must be connected to V+. It should not be used as the sole V+ connection.
