DG211BDY-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG211BDY-E3 is a quad single-pole single-throw (SPST) normally closed analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from +4.5 V to +25 V, or dual supplies from ±4.5 V to ±22 V. The device features a maximum drain-source on-resistance of 85 Ω at room temperature and up to 100 Ω across the full operating temperature range of -40 °C to +85 °C. Switching times are specified with a maximum turn-on time of 300 ns and a maximum turn-off time of 200 ns. The package is a 16-pin Narrow SOIC.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'E3' confirms lead-free and RoHS compliance status as defined in the manufacturer's documentation. Confirm the 'D' suffix indicates the -40 °C to +85 °C extended temperature range. Ensure the 'Y' suffix matches the required 16-pin Narrow SOIC package type for the specific board layout requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed signal path is required, distinguishing it from the DG212B which is normally open. Verify that the 85 Ω on-resistance meets the application's signal integrity needs compared to lower resistance alternatives. Ensure the power supply rails fall within the continuous operation range of ±4.5 V to ±22 V.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG211B/DG212B series, representing improved versions of the industry-standard DG211/212 switches. Manufactured using a proprietary silicon gate CMOS process, the B-series offers lower on-resistance, lower leakage, higher speed, and reduced power consumption compared to previous generations.
