DG201BDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201BDJ is a quad single-pole single-throw (SPST) analog switch fabricated in Vishay Siliconix's silicon gate CMOS process. It operates with dual supplies 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 200 Ω across the full operating range. Switching times are specified as a maximum turn-on time of 300 ns and a maximum turn-off time of 200 ns. It utilizes a 16-pin plastic DIP package and supports an extended industrial temperature range from -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against the manufacturer's ordering information to confirm the package type and temperature rating. Confirm RoHS compliance status, as non-compliant terminations may apply depending on the manufacturing lot. Validate that the component meets the required lead configuration for the target printed circuit board layout before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a normally closed SPST configuration is required within the DG201B family. Ensure the application voltage does not exceed the ±22 V limit for continuous operation. Verify that the logic interface levels match the TTL and CMOS compatibility specifications provided in the datasheet for proper control signal integration.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG201B series, which serves as an improved version of the industry-standard DG201A. It offers lower on-resistance, reduced leakage, higher speed, and lower power consumption compared to its predecessor. The device is designed for applications requiring wide analog signal ranges and simple logic interfaces.
