DG441DY-T1

Overview

The DG441DY-T1 is a CMOS analog switch IC from the Vishay Siliconix DG441 series, housed in a 16-pin SOIC surface-mount package. It integrates four independent single-pole single-throw (SPST) channels. The device supports dual supply voltages of ±15 V and operates within an ambient temperature range of -40°C to +85°C. Key electrical specifications include a maximum on-resistance of 85 Ohms, a maximum power dissipation of 900 mW, and a maximum supply current of 100 µA. Switching performance is characterized by a maximum turn-on time of 250 ns and a maximum turn-off time of 120 ns.

Feature Summary

Integrates four independent SPST analog switches on a single monolithic CMOS chip
Supports dual supply voltage operation for flexible signal routing
Features low power consumption with minimal supply current draw
Designed for surface-mount assembly in standard industrial temperature ranges

Applications

Data acquisition systems requiring multi-channel signal switching
Industrial process control instrumentation
Automotive test equipment signal paths
Medical diagnostic devices

Procurement Notes

Verify the specific suffix T1 against official manufacturer documentation to confirm tape-and-reel packaging configuration. Ensure the component meets RoHS compliance requirements as indicated in the datasheet. Cross-reference the full part number with authorized distributors to confirm current availability status and lead times.

Selection Notes

Select this component when four isolated SPST switching functions are required in a compact SOIC-16 footprint. Compare the 85 Ohm on-resistance and 250 ns switching speed against application bandwidth requirements. Consider the 900 mW power dissipation limit for thermal management in dense PCB layouts.

Part Context

This part belongs to the DG441 family of quad SPST analog switches manufactured by Vishay Siliconix. The DG441 series provides a cost-effective solution for general-purpose analog signal routing. The DY suffix denotes the SOIC-16 package variant, distinguishing it from other package options like LDQ or BDN available within the same functional family.
