The ISO1540QDRQ1 from Texas Instruments is an automotive digital isolator with an isolated bidirectional clock and a bidirectional I2C isolator. This part is rated to 2.5-kVrms isolation voltage and offers up to 16 Mbps channel data rate. It comes in an 8-pin SOIC package, operating from -40 to 125C. The part is designed for high speed, high isolation analog signal isolation, bidirectional data transfer, isolated bus communication, and fault protection. It features input/output monitoring with a diagnostic output for failing inputs, short circuit protection, and over temperature/current protection. It also includes a common enable pin to turn off both channels simultaneously. The part is an ideal choice for applications such as communication line and power line isolation, avionics, heavy industry, medical instruments, and automotive systems.
