DG2038DS-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2038DS-T1-E3 is a dual single-pole/single-throw (SPST) monolithic CMOS 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 maximum on-resistance of 6 Ω at 5.5 V. The device provides fast switching with a maximum turn-on time of 35 ns and a maximum turn-off time of 31 ns. It utilizes an MSOP-8 surface-mount package and supports an operating temperature range from -40 °C to +85 °C. The component draws a maximum supply current of 1 µA, making it suitable for low-power applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'DS' indicates the SOT-23-8 package variant rather than the MSOP-8 package associated with the 'DQ' suffix. Confirm RoHS compliance status through official documentation as standard manufacturing practices may vary. Ensure the ordering information matches the required pinout and physical dimensions for the target PCB layout before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel analog switch is required within a compact footprint. The low on-resistance and fast switching times make it appropriate for high-performance signal routing in portable devices. Verify that the input voltage levels align with the system's logic thresholds and that the supply voltage remains within the specified 1.8 V to 5.5 V operational range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2037/2038/2039 family of low-voltage analog switches. The DG2038 variant specifically offers inverted logic control compared to the DG2037. These components are designed using a high-density low-voltage process with an epitaxial layer to prevent latchup, ensuring reliable operation in battery-powered environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG2037DS-T1-E3: Similar dual SPST switch but with non-inverted logic control. DG2039DS-T1-E3: Dual SPST switch with complementary logic control where one channel is normally on and the other is normally off.
