DG201BDY-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201BDY-T1 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix in a 16-pin narrow SOIC package. It operates with dual supply voltages ranging from ±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 100 Ω across the full operating temperature range (-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 component supports continuous current ratings of 30 mA and includes an epitaxial layer to prevent latchup.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T1' indicates reel packaging when sourcing this component. Confirm RoHS compliance status, as non-compliant variants may exist within the same family. Ensure the narrow SOIC-16 footprint matches the target PCB layout requirements before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG201BDY-T1 when a normally closed analog switch topology is required for signal routing. Compare the 85 Ω on-resistance against circuit tolerance limits. Verify that the ±22 V supply rating aligns with the system's voltage rails. Consider the 300 ns turn-on time for high-speed signal processing requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG201B series, representing an improved version of the industry-standard DG201A. Manufactured using a proprietary silicon gate CMOS process, it offers lower on-resistance, reduced leakage, and faster switching speeds compared to previous generations while maintaining compatibility with standard logic families.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG201BDJ-T1 serves as a direct replacement offering the same electrical characteristics in a plastic DIP package. For surface-mount applications requiring a smaller footprint, the DG201BDQ-T1 provides identical functionality in a TSSOP-16 package.
