HCPL-901J-500

Digital Isolators Overview

The HCPL-901J-500E is a general-purpose digital isolator featuring four independent channels in a 16-SOIC package. It provides an isolation voltage of 2500 Vrms and supports data rates up to 110 MBd with a common-mode transient immunity of 15 kV/µs. The device operates on a supply voltage range of 3 V to 5.5 V, drawing typical currents of 1.5 mA or 3 mA per channel depending on the logic state. It functions within a temperature range of -40°C to +100°C and exhibits a propagation delay of approximately 15 ns.

Digital Isolators Feature Summary

• High channel density with four isolated channels in a compact 16-pin surface-mount package
• Bidirectional signal transmission capability for flexible interface design
• Magnetic coupling isolation technology ensuring robust noise immunity
• Wide operating temperature range suitable for industrial environments

Digital Isolators Applications

• Isolating data conversion devices such as ADCs and DACs
• Protecting parallel buses in industrial control systems
• Peripheral interface isolation in embedded systems
• Digital fieldbus isolation applications

Digital Isolators Procurement Notes

Verify the specific suffix '500' indicates the reel packaging configuration when ordering. Confirm that the component meets RoHS compliance requirements for your region. Ensure the 16-SOIC footprint matches your PCB layout constraints. Check for any recent product change notices regarding pinout or electrical characteristics from Broadcom.

Digital Isolators Selection Notes

Select this component when high channel density is required alongside moderate speed performance. The 2500 Vrms rating suits standard industrial isolation needs. Consider the 15 ns propagation delay for timing-sensitive designs. The bidirectional nature simplifies circuit topology compared to unidirectional alternatives.

Digital Isolators Part Context

This part belongs to the HCPL-900J series of digital isolators from Broadcom. The series includes variants like HCPL-901J and HCPL-091J, differing primarily in channel count and package options. These devices utilize magnetic coupling technology rather than optical or capacitive methods, offering distinct reliability characteristics for high-speed digital isolation tasks.

Digital Isolators Replacement Considerations

Direct substitutes include HCPL-901J without the '500' suffix if tape-and-reel packaging is not mandatory. HCPL-091J may serve as an alternative if different packaging is acceptable. Verify pin compatibility and electrical specifications before swapping.
