TI ISO7710FQDRQ1

The ISO7710-Q1 device is a high-performance single-channel digital isolator that provides isolation ratings of 5000 VRMS (DW package) and 3000 VRMS (D package) in accordance with UL 1577. This device is also certified by VDE, TUV, CSA, and CQC. While isolating complementary metal-oxide-semiconductor (CMOS) or low-voltage complementary metal-oxide-semiconductor (LVCMOS) digital I/Os, the ISO7710-Q1 device offers high electromagnetic immunity, low emissions, and low power consumption. The isolated channels feature logic input and output buffers, which are isolated by a silicon dioxide (SiO₂) insulation barrier. In case of input power or signal loss, devices without the suffix F default to a high output, while those with the suffix F default to a low output. When used in conjunction with an isolated power supply, this device helps prevent noise currents in the data bus or other circuits from entering the local ground, which could otherwise interfere with or damage sensitive circuits. Thanks to the innovative die design and routing techniques, the electromagnetic compatibility of the ISO7710-Q1 device is significantly enhanced, mitigating system-level ESD, EFT, and surge issues and meeting radiated standards. The ISO7710-Q1 device is available in 16-pin SOIC wide-body (DW) and 8-pin SOIC narrow-body (D) packages.
