TIISO7721DWR
Overview
The ISO7721DWR is a high-performance, dual-channel digital isolator providing 5000Vrms isolation in a wide-body SOIC-16 package. It utilizes TI's capacitive silicon dioxide (SiO2) barrier technology to enable high-speed data transmission up to 100Mbps with excellent electromagnetic immunity. This device features one forward and one reverse channel, making it ideal for bidirectional control signaling in harsh environments.
Why Choose This Part
It offers a high common-mode transient immunity (CMTI) of 100kV/us, ensuring reliable data integrity in electrically noisy environments. The device is highly efficient with a low power consumption of approximately 1.7mA per channel at 1Mbps and supports a wide logic supply range from 2.25V to 5.5V for flexible level translation.
Applications
Key Specifications
Getting Started
To evaluate this component, use the ISO7721EVM evaluation module which provides easy access to all pins via headers and SMA connectors for signal integrity testing. Ensure that 0.1uF bypass capacitors are placed as close as possible to the VCC pins on both the primary and secondary sides to maintain stability during high-speed switching.
