TIISO7342FCDWR
Overview
The ISO7342FCDWR is a quad-channel, high-performance digital isolator providing 3000Vrms isolation. It features two forward and two reverse channels, supporting data rates up to 25Mbps while maintaining robust electromagnetic compatibility and low power consumption. This device is designed to protect sensitive circuitry from high-voltage transients and ground loops in harsh industrial environments.
Why Choose This Part
This isolator offers high transient immunity of 70kV/us and integrated noise filters on inputs to ensure reliable data transmission in electrically noisy environments. It is highly efficient, drawing only 4.3mA per channel at 3.3V while operating at 25Mbps, and includes a default-low output state for predictable system behavior during power loss.
Applications
Key Specifications
Getting Started
Engineers can evaluate this part using the ISO734x-EVM evaluation module from Texas Instruments. When designing the PCB, ensure at least 8mm of creepage and clearance is maintained between the isolated grounds and place 0.1uF bypass capacitors as close to the VDD pins as possible.
