) flows through the input LED, it emits infrared light. This light travels across an optically transparent but electrically isolating barrier to hit the photodetector. The detector amplifies this signal and switches the output state at Pin 6 (and Pin 7 if dual-channel), mirroring the input logic without any physical electrical contact. 3. Absolute Maximum Ratings
