DG411HSDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411HSDJ is a precision monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It operates within a supply voltage range of ±5 V to ±20 V or +5 V to +44 V, supporting an analog signal range of ±15 V. The device features a maximum on-resistance of 35 Ω and fast switching times with a turn-on time of 68 ns and turn-off time of 42 ns at room temperature. Designed for low power consumption, it draws only 0.35 µW. The component utilizes a high-voltage silicon-gate process with an epitaxial layer to prevent latch-up. It is housed in a 16-pin plastic dual-in-line package and supports TTL and CMOS logic inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and compliance status. The 'DJ' suffix indicates a 16-pin plastic DIP package. Confirm RoHS compliance requirements; standard versions may contain lead, while '-E3' variants are lead-free. Ensure the operating temperature range matches the application environment, as the 'D' suffix specifies operation from -40 °C to +85 °C. Cross-reference pin configurations if replacing legacy components like the DG211 series.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG411HSDJ when low charge injection and high off-isolation are required for precision signal routing. The negative control logic distinguishes it from positive logic counterparts like the DG412. Consider the 35 Ω on-resistance variation over temperature and signal voltage when designing for minimal insertion loss. Verify that the 44 V maximum supply rating accommodates peak transient voltages in the target circuit. Evaluate thermal dissipation limits based on the specific PCB layout and ambient conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG411HSDJ belongs to the DG411HS family, which serves as a drop-in replacement for the older DG211 and DG212 series devices. This family offers improved performance characteristics, including lower on-resistance and faster switching speeds compared to its predecessors. The HS designation denotes the high-voltage silicon-gate process technology used to achieve superior reliability and latch-up immunity. The component is part of a broader portfolio that includes variants with different logic polarities and packaging options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411HSDJ is functionally equivalent to the DG211 series for direct replacement purposes. Designers should verify logic polarity differences if substituting for DG212 devices. Alternative packages such as SOIC (DG411HSDY) or QFN (DG411HSDN) offer the same electrical specifications but require appropriate footprint adjustments.
