DG421DJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG421DJ is a dual single-pole/single-throw (SPST) CMOS analog switch housed in a 16-pin plastic DIP package. It operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies, supporting rail-to-rail signal handling. The device features latchable logic inputs for simplified microprocessor interfacing and guarantees an on-resistance of 35Ω maximum with a matching tolerance of 3Ω between channels. It provides fast switching times of 250ns turn-on and 200ns turn-off, low power consumption of 35µW maximum, and charge injection of 15pC maximum.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'DJ' corresponds to the 16-pin Plastic DIP package and the -40°C to +85°C operating temperature range. Confirm the component status as obsolete or discontinued before initiating procurement actions. Ensure compatibility with existing PCB footprints designed for standard 16-pin DIP configurations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPST switching with latched control signals is required. Verify that the application can accommodate the specified 35Ω maximum on-resistance and 15pC charge injection limits. Ensure the system design supports the necessary bipolar or single-supply voltage ranges for proper operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG421/DG423/DG425 family of improved low-power CMOS analog switches. The DG421 variant specifically provides two independent SPST switches within a single package. It was redesigned to offer better on-resistance flatness and lower off-leakage current compared to previous industry-standard versions.
