DG303BDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG303BDJ is a dual-channel CMOS analog switch manufactured by Vishay Siliconix, housed in a 14-pin PDIP package. It features two independent SPST switches with both normally open and normally closed configurations. The device operates on dual supplies up to ±15V or single supplies up to 36V. Key electrical parameters include a maximum on-resistance of 50 ohms, charge injection of 8pC, and leakage current of 1nA. Switching times are specified at 300ns for turn-on and 250ns for turn-off. The component supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

This component has reached end-of-life status and is no longer manufactured by the original producer. Verification of availability requires checking authorized distributors for remaining stock or obsolete inventory. Buyers must confirm the specific manufacturing date code and physical condition before procurement due to the discontinued nature of the part.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Designers requiring this specific pinout and electrical profile should evaluate the DG303ACJ+ as a verified alternative from Analog Devices/Maxim Integrated. Selection criteria must account for the transition from the original Vishay Siliconix production to the current manufacturer while maintaining compatibility with existing board layouts and thermal requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG303BDJ belongs to the DG303 series of TTL-compatible CMOS analog switches. This family is characterized by its robust switching capabilities and compatibility with standard logic families. The BDJ suffix specifically denotes the through-hole PDIP-14 packaging variant used in legacy industrial and test equipment designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG303ACJ+ from Analog Devices Inc./Maxim Integrated is listed as a similar replacement part. Engineers should verify pin-to-pin compatibility and parameter tolerances against the original datasheet specifications before implementing this substitute in existing hardware designs.
