DG202BDQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG202BDQ-T1-E3 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates with a 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 on-resistance of 85 Ω at room temperature and up to 200 Ω across the full operating temperature range. Switching times are specified with a maximum turn-on time of 300 ns and a maximum turn-off time of 200 ns. It utilizes a TSSOP-16 surface-mount package and supports an extended industrial temperature range from -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix matches the required tape-and-reel packaging format and lead finish specifications. Confirm the RoHS compliance status aligns with current regulatory requirements for the target market. Ensure the component lot date code meets project timeline constraints before finalizing purchase orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a normally open SPST configuration is required for analog signal paths. The DG202B variant differs from the DG201B, which provides a normally closed function. Verify that the system logic levels are compatible with the specified input voltage thresholds for reliable switching operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG201B/DG202B family of improved quad CMOS analog switches. These devices supersede earlier industry-standard models by offering lower on-resistance, reduced leakage currents, and faster switching speeds while maintaining compatibility with standard TTL and CMOS logic interfaces.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG202BDQ is the non-tape version of this component in the same TSSOP-16 package. The DG202BDY serves as the equivalent alternative in the narrow SOIC-16 package.
