The use of digital isolator in industrial sector is expected to dominate the market because the digital isolator proves to be a vital means of receiving efficient and low-cost solutions for equipment safety and data transfer compared to optocouplers. They are used in several sectors such as industrial, healthcare, automotive, and telecommunications. It has a wide application in gate drivers, DC/DC converters, ADCs, USB & other communication ports, and CAN isolation.
Digital isolator is comparatively faster and less error prone. Optocoupler is far too slow and error prone for high speed (1MHz+) digital signals. It is used as a substitute to optocouplers. These isolators employ RF coupling techniques to transmit digital information across an isolation barrier.

Iso Design W/ 16-kV Contact Discharge ESD Protection Improve Your System Performance by Replacing Optocouplers with Digital Isolators (Rev. ISO776x High-speed, robust EMC, reinforced six-channel digital isolators datasheet (Rev. The ISO776x family of devices is available in 16-pin SOIC and SSOP packages. Through innovative chip design and layout techniques, electromagnetic compatibility of the ISO776x family of devices has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. Used in conjunction with isolated power supplies, this family of devices helps prevent noise currents on data buses, such as RS-485, RS-232, and CAN, or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. See the Device Functional Modes section for further details. If the input power or signal is lost, the default output is high for devices without suffix F and low for devices with suffix F. The ISO776x family of devices is available in all possible pin configurations such that all six channels are in the same direction, or one, two, or three channels are in reverse direction while the remaining channels are in forward direction. Each isolation channel has a logic-input and logic-output buffer separated by a double capacitive silicon dioxide (SiO 2) insulation barrier. The ISO776x family of devices provides high-electromagnetic immunity and low emissions at low-power consumption, while isolating CMOS or LVCMOS digital I/Os.
This family of devices is also certified according to VDE, CSA, TUV and CQC. The ISO776x devices are high-performance, six-channel digital isolators with 5000-V RMS (DW package) and 3000-V RMS (DBQ package) isolation ratings per UL 1577.
