ISO7330CQDWQ1 Texas Instruments

Overview

The ISO733x family of devices 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 three isolated channels comprised of logic input and output buffers separated by a silicon dioxide (SiO₂) insulation barrier.

The ISO7330 has all three channels in the same direction while ISO7331 has two channels in forward and one channel in reverse direction. See the section for further details.

Used in conjunction with isolated power supplies, these devices prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. The ISO733x family of devices has integrated noise filter for harsh industrial environment where short noise pulses may be present at the device input pins. The ISO733x family of devices has TTL input thresholds and operates from 3-V to 5.5-V supply levels. Through innovative chip design and layout techniques, electromagnetic compatibility of the ISO733x family of devices 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.
