DG202BDY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG202BDY is a quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It features four independent channels in a 16-pin SOIC package. The device supports single supply voltages from 0 V to 12 V or dual supplies ranging from ±4.5 V to ±11 V. Key electrical parameters include a maximum on-resistance of 85 Ohms, a maximum power dissipation of 640 mW, and a maximum supply current of 50 uA. Switching times are specified at a maximum of 300 ns for turn-on and 200 ns for turn-off. The component operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates four independent SPST analog switches in a compact surface-mount package.
• Operates with low supply current suitable for battery-powered applications.
• Provides high input impedance and low charge injection characteristics typical of CMOS technology.

Analog Switches, Multiplexers, Demultiplexers Applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix and RoHS compliance status before procurement, as the base part number may have multiple variants. Confirm availability through authorized distributors, noting that some listings indicate limited stock or discontinued status for certain packaging options. Ensure the selected variant matches the required lead time and manufacturing origin.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with moderate on-resistance. Compare against the DG201 series for similar performance or the DG202BDQ if a TSSOP package is preferred. Verify that the 85 Ohm on-resistance meets the signal integrity requirements of the application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG20x family of improved quad CMOS analog switches. It shares functional similarities with other members like the DG201 and DG202BDQ but differs in package type and specific electrical tolerances. The DG202BDY utilizes an SOIC-16 footprint, distinguishing it from shrink-package alternatives in the same product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG202BDQ-E3 serves as a pin-compatible alternative in a TSSOP-16 package. Other potential substitutes include parts from the DG201 series or generic quad SPST CMOS switches with matching voltage and resistance specifications.
