DG2037DS-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2037DS-T1 is a dual single-pole/single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and features a low on-resistance of 3.0 Ω at 2.7 V. The device provides fast switching with turn-on and turn-off times of approximately 12 ns, alongside low charge injection of 10 pC. It is housed in an SOT-23-8 surface-mount package and supports an operating temperature range from -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and environmental compliance. Confirm availability status as distribution channels may vary. Ensure the component meets the required operating temperature range and electrical specifications for the intended design application before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low voltage operation between 1.8 V and 5.5 V is required. The DG2037 offers a normally-open configuration compared to other variants in the series. Consider the SOT-23-8 package for space-constrained designs requiring dual SPST switching functionality with minimal board footprint.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2037/2038/2039 family of low-voltage analog switches. The DG2037 variant specifically provides two normally-open switches, distinguishing it from the DG2038 (normally-closed) and DG2039 (one normally-open, one normally-closed). All share the same physical package and core electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for DG2038DS or DG2039DS if different switch logic states are acceptable. Verify pin compatibility and electrical parameters against alternative dual SPST analog switches from other manufacturers if the DG2037DS-T1 is unavailable.
