DG403BDY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG403BDY is a monolithic analog switch from the Vishay Siliconix DG401B/403B/405B series, housed in a 16-pin narrow SOIC package. It contains four independent SPST switches configured in normally open/normally closed (NO/NC) pairs. The device operates with dual supplies up to ±15 V and supports single supply operation. 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. It features low leakage currents and is designed for TTL and CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix when sourcing this component. The base model DG403BDY typically denotes the standard commercial version without lead-free terminations. Ensure the required RoHS compliance status matches the project specifications before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG403BDY for applications requiring four isolated analog channels with complementary switching states. Verify that the 45 Ω maximum on-resistance meets the signal loss requirements. Confirm that the 16-pin SOIC footprint aligns with the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG401B/403B/405B family of high-speed CMOS analog switches. These devices serve as performance upgrades over the legacy DG401/403/405 series, offering improved speed and lower power consumption while maintaining similar pinouts and functionality.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG403BDY-E3 is the direct lead-free equivalent within the same package and specification set. Designers should verify if the absence of lead-free terminations in the non-E3 variant affects regulatory compliance for the target assembly.
