DG401BDY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG401BDY is a Vishay Siliconix low-power, high-speed CMOS analog switch housed in a 16-pin narrow SOIC package. It contains two independent single-pole single-throw (SPST) switches. The device supports a maximum supply voltage of 44 V and an analog signal range of ±15 V. Key electrical parameters include a maximum on-resistance of 45 Ω, a typical turn-on time of 100 ns, and a maximum turn-off time of 100 ns. Operating temperature ranges from -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity and pin alignment prior to installation. Ensure storage conditions meet specified humidity and temperature limits to maintain reliability during handling and assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPST switching is required within a compact surface-mount footprint. Evaluate thermal dissipation requirements as power derating applies above 75 °C. Verify that input logic levels align with system control voltages to ensure proper switching thresholds are met during operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG401B series, which serves as an improved replacement for the legacy DG401 model. It utilizes Vishay's proprietary high-voltage silicon-gate process to achieve superior performance characteristics compared to previous generations while maintaining similar functional configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG401BDY-E3 is the lead-free variant of this component. Verify if RoHS compliance is required for the target application before selecting between standard and lead-free terminations.
