Overview
The DG403EJ is a monolithic CMOS analog switch manufactured by Harris Corporation, part of the DG series. It features four independent single-pole single-throw (SPST) switches in a 16-pin DIP package. The device operates with dual supplies ranging from ±15V to ±20V or a single supply up to 30V. Key electrical parameters include a maximum on-resistance of 45 ohms, a maximum on-resistance difference of 10 ohms, and a typical leakage current of 1 nA at +25°C. Switching times are specified with a maximum turn-on time of 150 ns and turn-off time of 100 ns. The component supports a continuous DC switch current of 30 mA and dissipates up to 600 mW of power.
Feature Summary
- Monolithic CMOS construction providing high input impedance and low power consumption.
- Four independent SPST channels allowing flexible signal routing configurations.
- Low leakage current characteristics suitable for precision analog applications.
- Compatible with standard TTL and CMOS logic levels for control inputs.
Applications
- Multiplexing audio and video signals in test equipment.
- Sample-and-hold circuits in data acquisition systems.
- Programmable gain amplifiers and attenuators.
- Gate drivers for power MOSFETs and IGBTs.
Procurement Notes
Verify the manufacturer origin carefully, as Harris Semiconductor assets were acquired by Intersil and subsequently Renesas. Ensure the specific lot date code aligns with project requirements due to potential end-of-life status. Confirm RoHS compliance if required, as original Harris parts may not meet modern environmental standards. Request full datasheet verification to confirm pinout and electrical tolerances match the design specifications before integration.
Selection Notes
Select this component when four isolated analog paths are required within a single package. Compare on-resistance stability over temperature against alternatives if linearity is critical. Verify that the control voltage levels match the available logic supply rails. Consider the PDIP-16 package constraints for thermal management given the 600 mW power dissipation rating in enclosed environments.
Part Context
The DG403 belongs to the Harris DG4xx family of analog switches, which were industry standards for general-purpose signal switching. Harris Corporation was a primary developer of these CMOS switches before its semiconductor division was acquired. This part represents a legacy component often found in existing industrial and military designs requiring reliable analog switching capabilities.
Replacement Considerations
Direct replacements include the DG403IDN (SOIC package) or DG403EY. Cross-reference with Intersil ISL40808 or Maxim MAX358 for modern equivalents. Verify pin compatibility and electrical parameter overlaps before substitution. Check for updated RoHS compliance in newer manufacturing runs.
