DG2501DB-T2-GE1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2501DB-T2-GE1 is a monolithic quad single-pole single-throw (SPST) analog switch from Vishay Siliconix. It operates on a single 1.8 V to 5.5 V power supply and features four independently selectable switches with closely matched channel resistance. The device guarantees break-before-make operation for multiplexer applications. Electrical characteristics are specified at 3 V and 5 V, with an on-resistance maximum of 200 Ω at room temperature and 250 Ω across the full operating range (-40 °C to +85 °C). It offers low leakage current (max 1 nA at 85 °C), high ESD tolerance (>8 kV HBM), and rail-to-rail signal handling.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel quantity. Confirm that the component meets RoHS compliance requirements for the intended manufacturing process. Ensure the supplier provides traceability data consistent with Vishay's quality standards. Validate that the received parts match the exact part number designation before integration into production lines.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed quad SPST configuration is required within a compact footprint. It is suitable for portable designs due to its ultra-low typical power consumption. Verify that the control logic thresholds align with the system voltage levels, as they vary between 3 V and 5 V supplies. Consider the WCSP16 package dimensions for PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG250x family of low-leakage analog switches, which also includes the DG2502 (normally open) and DG2503 (mixed NC/NO). All variants share identical electrical specifications and packaging but differ in their default switch states. The DG2501 specifically provides a fully normally closed architecture for all four channels.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG2502DB-T2-GE1: Identical electrical specs but configured as Normally Open (NO). DG2503DB-T2-GE1: Identical electrical specs but configured with two Normally Open and two Normally Closed switches.
