This combination suits it for breaking ground loops and level-shifting digital signals in industrial fieldbus interfaces, motor-drive feedback paths, and medical equipment where patient isolation is required. Both input channels are on side 1 of the isolation barrier, making the part a unidirectional isolator for two independent downstream logic receivers. ## Timing and transient immunity for noisy environments Propagation delay is 75 ns max for both low-to-high and high-to-low transitions, with typical rise and fall times of 30 ns and 10 ns respectively. This timing budget allows the part to pass 10 Mbps NRZ data with adequate margin for clock recovery in most UART and SPI isolation applications. Common-mode transient immunity is specified at 5 kV/µs minimum. In a motor-drive or inverter environment where the output side reference jumps several hundred volts in a few nanoseconds, this rating ensures the receiver does not falsely trigger on the edge — a key parameter for maintaining data integrity across the barrier. ## Package, temperature grade, and compliance Housed in an 8-SMD gull-wing package (supplier device package 8-SMD), the part is intended for surface-mount assembly with standard reflow profiles. The -40°C to 110°C operating temperature range covers industrial enclosures, outdoor telecom cabinets, and under-hood automotive auxiliary circuits.","metaTitle":"onsemi HCPL2631SDM Optoisolator, 10Mbps, 5kVrms, 8-SMD","metaDescription":"onsemi HCPL2631SDM dual-channel open-collector optoisolator, 10 Mbps data rate, 5 kVrms isolation, 8-SMD gull wing.
