Texas Instruments ISO7810 Single-Channel Digital Isolators

Texas Instruments ISO7810 Single-Channel Digital Isolators are single-channel digital isolators with 8000V_PK isolation voltage. These devices have reinforced isolation certifications according to VDE, CSA, and CQC. Each isolator provides high electro-magnetic immunity. They also have low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/O's. Each isolation channel has a logic input and output buffer separated by silicon dioxide (SiO₂) insulation barrier. If the input power or signal is lost, default output is 'high' for the ISO7810 and 'low' for the ISO7810F device. Used in conjunction with isolated power supplies, this device prevents noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry.
