DG211BDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG211BDJ is a quad single-pole single-throw (SPST) analog switch from Vishay Siliconix, housed in a 16-pin plastic DIP package. It operates on a dual supply ranging from ±4.5 V to ±22 V or a single supply of +4.5 V to +25 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 range of -40 °C to +85 °C. Key electrical characteristics include a turn-on time of 300 ns, turn-off time of 200 ns, charge injection of 1 pC, and an off-isolation of 90 dB at 100 kHz. Supply current is limited to 10 µA typical.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the package type and lead finish. The base part number corresponds to the standard PDIP-16 variant. Confirm RoHS compliance status by checking for the designated suffix if environmental regulations are a strict requirement for the target assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed analog switch topology is required within the DG211B family. Ensure the application voltage does not exceed the ±22 V continuous operation limit. Verify that the 85 Ω on-resistance meets the signal integrity requirements compared to lower resistance alternatives like the DG213 series.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG211B/DG212B series, representing improved versions of the industry-standard DG211 and DG212 switches. Manufactured using a proprietary silicon gate CMOS process, it offers lower on-resistance, reduced leakage, and higher speed compared to its predecessors while maintaining pin compatibility.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG211BDQ serves as a surface-mount equivalent in the TSSOP-16 package. For applications requiring normally open functionality, the DG212BDJ is the direct functional counterpart within the same package.
