Texas Instruments ISO6521REUR Dual-Channel Functional Isolator

Texas Instruments ISO6521REUR Dual-Channel Functional Isolator is a high-performance device with an isolation barrier that supports a 200V_RMS/280V_DC working voltage and 570V_RMS/800V_DC transient overvoltage. This digital isolator offers high electromagnetic immunity and low emissions at low power consumption. The ISO6521REUR isolator prevents noise currents on data buses, such as SPI, UART, RS-232, RS-485, and CAN from damaging sensitive circuits. This isolator features a 50Mbps data rate, 1.71V to 5.5V level translation, and 11ns typical low propagation delay at 3.3V.

The ISO6521REUR isolator operates within a -40°C to 125°C temperature range and is available in 3mm x 2mm dimensions. This isolator is ideal for space-constrained applications that require isolation for non-safety applications. The ISO6521REUR isolator is used in power supplies, motor drives, factory automation, building automation, lighting, and electricity meters.
