DG444CJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG444CJ is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed switches with an on-resistance of 85 ohms maximum and an on-resistance match between channels of 4 ohms maximum. The device operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. Key electrical parameters include a turn-on time of 250ns maximum, a turn-off time of 120ns maximum, and charge injection of 10pC maximum. It is housed in a 16-pin Plastic DIP package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CJ' corresponds to the 16-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm RoHS compliance status as legacy parts may vary. Ensure the ordering code matches the manufacturer's current designation for this component variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG444CJ when a normally closed SPST configuration is required. Compare against the DG445CJ if a normally open configuration is needed instead. Consider the DG444DJ variant if operation in industrial temperatures down to -40°C is necessary. Verify that the 85 ohm on-resistance meets the circuit requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG444CJ belongs to the DG444/DG445 family of improved analog switches. This series was redesigned to offer better performance than industry-standard predecessors, specifically regarding on-resistance matching and flatness. The C suffix denotes the commercial temperature grade, while J indicates the plastic DIP package style.
