DG401CJ+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG401CJ+ is a dual, high-speed analog switch fabricated using a silicon-gate process. It features two single-pole/single-throw (SPST) normally open switches with rail-to-rail signal handling capability. The device operates from a single +10V to +30V supply or bipolar supplies of ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 45Ω and a typical value of 20Ω. On-resistance matching between channels is guaranteed at 2Ω maximum, while on-resistance flatness over the signal range is limited to 3Ω maximum. Switching times are specified as 150ns maximum for turn-on and 100ns maximum for turn-off. Charge injection is capped at 15pC, and off-leakage current remains below 5nA at +85°C. Power consumption is low at 35µW maximum.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix 'CJ' corresponds to the Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm compatibility with existing PCB footprints designed for 16-pin DIP configurations. Ensure logic levels align with TTL or CMOS standards depending on the VL pin voltage. Check for RoHS compliance status if required by specific manufacturing regulations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPST switching is required with tight on-resistance matching specifications. The device supports both single and bipolar power supplies, offering flexibility in system design. Consider the 45Ω maximum on-resistance and 150ns switching speed for bandwidth and latency requirements. Verify that the 0°C to +70°C operating range meets environmental conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG401CJ+ belongs to the redesigned DG401/DG403/DG405 family of improved dual high-speed analog switches. This series replaces older industry-standard versions while maintaining pin compatibility. The DG401 specifically provides two SPST switches, distinguishing it from the DG403 (SPDT) and DG405 (dual SPST with different configuration). The CJ suffix denotes the 16-pin Plastic DIP package variant within this product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include other variants within the DG401 family such as DG401CY or DG401DJ, provided the package and temperature range match the application requirements.
