Overview

The HCPL-090J-000E is a high-speed, four-channel digital isolator designed for data rates up to 110MBd. It utilizes Broadcom's GMR (Giant Magnetoresistive) technology to provide 2500Vrms isolation in a compact 16-pin SOIC package. This device is compatible with both 3.3V and 5.0V logic levels, making it ideal for bridging different voltage domains in high-speed digital systems.

Why Choose This Part

This isolator offers a high common-mode transient immunity (CMTI) of 15kV/us, ensuring reliable operation in electrically noisy environments. It features a low typical supply current of 5.5mA at 3.3V and provides a tri-state output for efficient multiplexing in multi-node systems.

Applications

Industrial Fieldbus Isolation
Provides high-speed galvanic isolation for protocols like Profibus, DeviceNet, and RS-485 to protect controllers from ground loops and transients.
High-Speed Logic Level Shifting
Seamlessly bridges data between 3.3V and 5V CMOS/TTL logic systems while maintaining signal integrity at high clock speeds.
Isolated ADC/DAC Interfaces
Protects sensitive analog-to-digital and digital-to-analog converter interfaces in noisy industrial environments.
Computer Peripheral Communication
Used in high-speed data acquisition systems to isolate PC interfaces from high-voltage external hardware.

Getting Started

When designing with this part, place 0.1uF bypass capacitors as close as possible to the VDD1 and VDD2 pins to minimize high-frequency noise. Ensure the PCB layout maintains the required creepage and clearance distances between the input and output sides to preserve the 2500Vrms isolation rating.
