The ISO7230M, manufactured by Texas Instruments, is a cutting-edge triple-channel digital isolator designed to provide high electromagnetic immunity and low emissions at low power consumption while isolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier.

Key Features

• High Isolation: With an isolation voltage of 2500 Vrms for 1 minute, the ISO7230M offers robust protection for sensitive circuits.
• Data Rates: This device supports data rates up to 25 Mbps, providing high-speed operation for a variety of digital communication applications.
• Channels: It includes three forward-direction channels, making it suitable for isolating SPI, I2C, or other digital control interfaces.
• Low Power Consumption: The ISO7230M operates efficiently with a typical quiescent supply current of 1.5 mA per channel at 5 V, minimizing power loss and heat generation.

Applications

The ISO7230M is designed for use in a variety of applications where digital signal isolation is critical, including:

• Industrial automation and control systems
• Medical equipment with patient electrical isolation
• Isolated SPI, I2C interfaces
• Isolated ADC and DAC
• Motor control circuits
