DG421DY

Overview

The DG421DY is a dual single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies, providing rail-to-rail signal handling capabilities. The device features a maximum on-resistance of 35Ω and guarantees an on-resistance match between channels of 3Ω maximum. It includes latchable logic inputs for simplified microprocessor interfacing. The component is housed in a 16-SOIC surface-mount package and supports an operating temperature range of -40°C to +85°C.

Feature Summary

Features latchable logic inputs that simplify direct interfacing with microprocessors.
Provides guaranteed low on-resistance matching between channels for improved signal integrity.
Supports both single-supply and bipolar power configurations for flexible system design.

Applications

Sample-and-Hold Circuits
Battery-Operated Systems
Audio Signal Routing

Procurement Notes

Verify the specific suffix 'DY' corresponds to the 16-pin SOIC package and the -40°C to +85°C industrial temperature grade. Confirm RoHS compliance status as the datasheet indicates potential variations based on manufacturing origin. Ensure the source document matches the official Maxim Integrated specifications for accurate parameter validation.

Selection Notes

Select this component when designing systems requiring precise analog switching with minimal channel-to-channel resistance variation. The integrated latches are advantageous for applications where control lines must maintain state without continuous refreshing. Verify that the required signal voltage swing remains within the specified rail-to-rail limits of the chosen supply configuration.

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 per package. This family was designed to offer enhanced performance over previous generations, particularly regarding on-resistance flatness and charge injection characteristics.
