Overview
The ISO7310FCDR is a low-power, single-channel digital isolator produced by Texas Instruments. This device is designed to provide galvanic isolation up to 3000 V RMS for 1 minute and 4242 V PK, ensuring robust protection against noise and electrical interference. It features a single isolated channel with a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier. The ISO7310FCDR operates from 3.3 V and 5 V supply levels, making it versatile for various applications. It is particularly useful in harsh industrial environments where noise pulses may be present, thanks to its integrated noise filters and enhanced electromagnetic compatibility (EMC).
