DG405BDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG405BDJ is a monolithic CMOS analog switch manufactured by Vishay Siliconix, serving as an enhanced replacement for the legacy DG405. It features four independent SPST switches arranged in two pairs within a 16-pin plastic DIP package. The device supports dual supply voltages up to ±15 V and single supplies up to 36 V, with a maximum rating of 44 V between rails. Key electrical parameters include a typical on-resistance (RDS(on)) of 23 Ω, a maximum of 45 Ω at room temperature, and low leakage currents of 40 pA. Switching performance is characterized by a typical turn-on time (tON) of 100 ns and a turn-off time (tOFF) of 60 ns.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Four independent SPST switches configured in two pairs

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and termination material. The standard commercial part number DG405BDJ corresponds to the 16-pin plastic DIP package. Ensure compatibility with lead-free requirements if applicable, noting that the -E3 suffix designates lead-free matte tin terminations. Confirm the operating temperature range matches the application environment before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG405BDJ when four independent single-pole single-throw channels are required in a through-hole package. This component is suitable for applications demanding high-speed switching with low power consumption. Verify that the analog signal range fits within the ±15 V limits and that the logic levels align with the TTL/CMOS compatible inputs. Consider the 16-pin DIP form factor for prototyping or legacy board designs.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG405BDJ belongs to the DG401B/DG403B/DG405B family of low-power, high-speed CMOS analog switches. These devices replace the older DG401/403/405 series, offering improved performance metrics such as faster switching speeds and lower power dissipation. The 'B' suffix indicates the enhanced version, while 'DJ' specifies the 16-pin plastic DIP package configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG405BDJ is designed as a direct upgrade for the legacy DG405. When replacing older components, verify pinout compatibility, as the functional block diagram remains consistent. Ensure that the new device's absolute maximum ratings, particularly regarding supply voltage and current limits, meet the system requirements.
