Overview
The DG442EJ is a high-speed quad single-pole single-throw (SPST) analog switch manufactured by Harris Corporation, part of the DG series. It features a multiplexer structure with four independent channels in a 16-pin DIP package. The device supports dual supply voltages ranging from ±15 V to ±15 V and operates within a temperature range of -40°C to +85°C. Key electrical specifications include a maximum on-resistance of 80 Ohms, a maximum propagation delay of 136 ns, and a maximum power supply current of 100 µA. It handles a DC switch current of 30 mA.
Feature Summary
- High-speed switching capability suitable for precision signal routing applications
- Quad SPST configuration providing four independent signal paths
- Low power consumption design with minimal supply current draw
Applications
- Data acquisition systems requiring precise analog signal selection
- Instrumentation circuits for sensor signal routing
- Communication equipment for channel switching
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing date codes upon order placement. Ensure proper handling procedures are followed during installation to prevent electrostatic discharge damage to the sensitive internal circuitry.
Selection Notes
Select this component when high-speed switching and low distortion are required for multiple analog signals. Compare on-resistance stability and leakage current specifications against alternative devices if operating conditions exceed standard ranges. Verify pin compatibility with existing PCB layouts before integration into new designs.
Part Context
This component belongs to the DG series of analog switches produced by Harris Corporation, which later became part of Intersil and subsequently Renesas Electronics. The DG442 variant specifically offers quad SPST functionality optimized for high-speed data acquisition and communication applications requiring reliable signal path management.
Replacement Considerations
Consider the DG442LDJ-E3 as a verified substitute offering identical functional specifications in a DIP-16 package. Verify pinout compatibility and electrical parameters before implementation.
