DG445DY-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG445DY-T1 is a quad single-pole single-throw (SPST) analog switch IC manufactured by Vishay Siliconix. It integrates four independent switches in a 16-pin SOIC package, supporting both single and dual power supplies ranging from 5 V to 36 V or ±2.5 V to ±18 V. The device features a maximum on-resistance of 85 Ohms and a typical charge injection of 0.7 nC. Key electrical parameters include a maximum operating frequency of 25 MHz, a maximum leakage current of 1 nA at 25°C, and a power dissipation of 640 mW. It operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability upon receipt. Check for physical damage to the SOIC-16 leads and ensure proper ESD handling procedures are followed during storage and installation to maintain device integrity.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring four isolated analog paths with moderate speed and low distortion. Ensure the supply voltage does not exceed the absolute maximum ratings. Consider thermal management if multiple switches operate simultaneously near the power dissipation limit. Verify that the load current remains within the specified continuous DC switch current limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG4xx series of high-speed analog switches from Vishay Siliconix. It shares functional similarities with the DG444 and DG445E3 variants but differs in packaging and specific electrical tolerances. The DG445DY-T1 is designed for applications needing reliable analog signal path control without digital interference.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations
