Features a GaAsP LED input and an integrated high-gain photodetector with an open collector output. Common Applications a1458 optocoupler datasheet
For digital logic interfaces (e.g., 5V to 3.3V), ranks A or B are sufficient. For analog applications or low I_F drive (e.g., 1 mA from a battery-powered MCU), ranks C or D provide higher sensitivity. This article is for informational purposes
The datasheet's typical rise/fall times are 4µs. To achieve this: 5V to 3.3V)
