✅ Component type/category matches: Optocoupler in DigiKey category Logic Output Optoisolators.
✅ Output Type: Open Drain, which is acceptable for the required Open Collector logic-output style.
✅ Number of Channels: 1, matches requirement.
✅ Voltage - Isolation: 3750Vrms, satisfies the ≥3000Vrms requirement.
✅ Data Rate: 10MBd, exceeds the ≥1MHz requirement and is more than sufficient for 115200 baud UART.
✅ Propagation Delay tpLH / tpHL (Max): 100ns, 100ns, well within the ≤10µs limit.
✅ Current - Output / Channel: 50mA, exceeds the ≥10mA requirement.
✅ Voltage - Forward (Vf) (Typ): 1.38V, satisfies the ≤1.5V requirement.
✅ Voltage - Supply: 2.7V ~ 3.6V, 4.5V ~ 5.5V; includes 3.3V, so it is compatible with the MCU supply requirement.
✅ Mounting Type: Surface Mount, matches requirement.
✅ Package / Case: 8-SOIC, matches the required compact SOIC-8 package.
✅ Operating Temperature: -40°C ~ 110°C, meets and exceeds the required industrial temperature range of -40°C to +85°C.
✅ RoHS Compliance: ROHS3 Compliant, satisfies requirement.
All required specifications are satisfied. This component is approved for the isolated 115200 baud UART TX application.
