Analog Switches, Multiplexers, Demultiplexers datasheet and documents for DG442DJ

DG442DJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442DJ is a quad, single-pole/single-throw (SPST) analog switch featuring four normally open switches. It operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. Key electrical parameters include an on-resistance of 85Ω maximum, on-resistance matching of 4Ω maximum between channels, and on-resistance flatness of 9Ω maximum over the signal range. The device guarantees low charge injection of 10pC maximum and off-leakage current less than 5nA at +85°C. Switching times are less than 250ns for turn-on and less than 170ns for turn-off. It provides rail-to-rail signal handling and is TTL/CMOS-logic compatible.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number is DG442. Add the plus symbol (+) to the end of the part number to specify lead-free packaging. Confirm the temperature range matches the design requirements, as the 'D' suffix indicates operation from -40°C to +85°C. Ensure the package type corresponds to the intended board layout.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG442DJ when a normally open switch configuration is required, as opposed to the normally closed DG441. Verify that the bipolar supply voltage range of ±4.5V to ±20V fits the system design. Consider the 85Ω maximum on-resistance for signal integrity requirements. Check if the 16-pin Plastic DIP package meets the physical constraints of the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG442DJ belongs to the redesigned DG441/DG442 series of improved quad SPST analog switches. These devices utilize a 44V silicon-gate process. The DG442 variant specifically features four normally open switches, distinguishing it from the DG441 which has four normally closed switches. Both share similar performance characteristics regarding on-resistance and switching speeds.
