General Purpose Digital Isolator 5000Vpk 2 Channel 100Mbps 50kV/µs CMTI 8-SOIC (0.295", 7.50mm Width) General Description The STISO621WTR is a high-performance quad-channel isolated digital input interface IC from STMicroelectronics. It is designed to interface industrial digital inputs (such as PLC inputs) with low-voltage logic systems while providing galvanic isolation for improved safety and noise immunity. This device integrates four independent input channels, each capable of handling high-voltage input signals, and converts them into isolated logic-level outputs. It is ideal for industrial automation, programmable logic controllers (PLCs), and factory control systems where robust signal isolation is required. Key Features Quad isolated digital input channels High common-mode transient immunity (CMTI) Wide input voltage range for industrial signals Integrated current limiting and protection circuitry Compatible with 3.3V and 5V logic outputs Low power consumption High noise immunity and ESD robustness Complies with industrial safety standards Electrical Characteristics Number of Channels: 4 Isolation Type: Galvanic isolation Input Voltage Range: Up to ~30 V (industrial input level) Logic Output Voltage: 3.3 V / 5 V compatible Propagation Delay: Typically low (tens of ns range) Supply Voltage (Vcc): 3.0 V to 5.5 V Operating Temperature Range: -40°C to +125°C Functional Description Each input channel accepts a high-voltage industrial signal and converts it into a corresponding isolated digital output. Internal circuitry provides: Input current limiting Signal conditioning Isolation barrier Output buffering The isolation barrier protects low-voltage control electronics from high-voltage transients, ground loops, and electrical noise.
