DG211BDY-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG211BDY-T1 is a quad single-pole single-throw (SPST) normally closed analog switch manufactured by Vishay Siliconix in a 16-pin narrow SOIC package. It operates on a dual supply voltage range of ±4.5 V to ±22 V or a single supply from +4.5 V to +25 V. The device features a maximum drain-source on-resistance of 85 Ω at room temperature, with a channel-to-channel matching of 2 Ω. Key dynamic characteristics include a turn-on time of 300 ns and a turn-off time of 200 ns. Supply current is limited to 10 µA, while the continuous current rating reaches 30 mA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T1' indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status by checking for the '-E3' designation if lead-free terminations are required. Ensure the ordering part number matches the exact package type and electrical specifications needed for the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring normally closed switching states within standard industrial temperature ranges. Compare against the DG212B variant if a normally open configuration is preferred instead. Verify that the 85 Ω on-resistance meets the signal integrity requirements of the connected analog paths.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG211B/DG212B series, which are improved versions of the industry-standard DG211 and DG212 devices. Manufactured using a proprietary silicon gate CMOS process, the series offers lower on-resistance, reduced leakage, higher speed, and lower power consumption compared to its predecessors.
