ISO652x/ISO652x-Q1 Functional Isolators

Texas Instruments ISO652x/ISO652x-Q1 Dual-Channel Functional Isolators are high-performance devices with an isolation barrier that supports a 200V_RMS/280V_DC working voltage and 570V_RMS/800V_DC transient overvoltage. These digital isolators offer high electromagnetic immunity and low emissions at low power consumption. The ISO652x/ISO652x-Q1 isolators prevent noise currents on data buses, such as SPI, UART, RS-232, RS-485, and CAN, from damaging sensitive circuits. These isolators feature a 50Mbps data rate, 1.71V to 5.5V level translation, and 11ns typical low propagation delay at 3.3V.
