66. UART Optoisolator Selection

Aarav is designing an industrial control board and needs to isolate a UART transmit signal between a noisy power section and a 3.3V microcontroller.

The UART communication speed is 115200 baud.

To transfer the logic signal safely across the isolation barrier, he wants a single-channel logic output optoisolator.

He prefers a compact SOIC-8 SMD package for PCB design.

Help him select a suitable logic output optoisolator from DigiKey.

Make sure it supports the required logic signal speed, provides enough isolation voltage, and works reliably in industrial temperatures.
