DG412DJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412DJ is a monolithic CMOS analog switch manufactured by Renesas Electronics Corporation. It integrates four independent single-pole single-throw (SPST) switches within a single package. The device supports both single and split power supply configurations, operating from +5V to +44V or ±5V to ±20V. It features a maximum on-resistance of 35 ohms and low power consumption. The component utilizes TTL and CMOS compatible digital inputs for control logic.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer source carefully, as the DG412 series has been produced by multiple entities including Intersil and Vishay. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Check for obsolescence notices or last-time buy notifications associated with this specific part number variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with high voltage handling capabilities up to 44V. Ensure the application logic matches the positive logic polarity of the DG412 series, distinguishing it from the negative logic DG411. Verify that the 35-ohm on-resistance meets the signal integrity requirements of the target circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG412DJ belongs to the DG41x family of monolithic CMOS analog switches. This family was developed to replace older DG211/DG212 technologies while offering improved performance characteristics such as lower on-resistance and faster switching speeds. The 'DJ' suffix typically denotes a 16-pin DIP package variant.
