Name: ISO7810DWR Optoisolators
Brand: Texas Instruments
SKU: ISO7810DWR

Overview

The ISO7810x device is a high-performance, single-channel digital isolator with 8000 V_PK isolation voltage. This device has reinforced isolation certifications according to VDE, CSA, CQC, and TUV. The isolator provides high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os.

The isolation channel has a logic input and output buffer separated by silicon dioxide (SiO₂) insulation barrier. If the input power or signal is lost, the default output is for the ISO7810 and for the ISO7810F device. See the Device Functional Modes section for further details.

Used in conjunction with isolated power supplies, this device helps prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. Through innovative chip design and layout techniques, electromagnetic compatibility of the ISO7810x device has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The ISO7810x device is available in 16-pin SOIC wide-body (DW) and extra-wide body (DWW) packages.The DWW package option comes with enable pin which can be used to put the output in high impedance state for multi-master driving applications and to reduce power consumption.

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.
