ISO7310FCQDRQ1 Texas Instruments

Overview

The ISO7310-Q1 device provides galvanic isolation up to 3000 V_RMS for 1 minute per UL 1577 and 4242 V_PKper VDE V 0884-10. These devices have one isolated channel comprised of a logic input and output buffer separated by a silicon dioxide (SiO₂) insulation barrier. Used in conjunction with isolated power supplies, the ISO7310-Q1 device prevents noise currents on a data bus or other circuit from entering the local ground and interfering with or damaging sensitive circuitry. The device has integrated noise filters for harsh industrial environment where short noise pulses may be present at the device input pins.

The ISO7310-Q1 device has TTL input thresholds and operate from 3-V to 5.5-V supply levels. Through innovative chip design and layout techniques, electromagnetic compatibility of the ISO7310-Q1 device has been significantly enhanced to enable system-level ESD, EFT, Surge and Emissions compliance.

For all available packages, see the orderable addendum at the end of the datasheet.

Wiki Reference

Optoelectronics, also known as optronics, is the field of study and application of electronic devices and systems that are used to detect, control, and manipulate light. It is often considered a subset of photonics. Optoelectronics encompasses the use of both visible light and invisible forms of radiation such as gamma rays, X-rays, ultraviolet, and infrared light. These devices can either convert electrical signals into optical signals, or vice versa. Optoelectronics relies on the quantum mechanical effects of light interacting with electronic materials, particularly semiconductors, often in the presence of electric fields. Key applications of optoelectronics include detecting and transmitting optical signals in various technologies.
