It is very common for the letters "PC" to be misread as "A" or for prefixes to be dropped in casual notation. The is a standard 4-pin optocoupler.
: Acts as a feedback element in switched-mode power supplies (SMPS) to maintain isolation. Motor Drives a1458 optocoupler datasheet
By converting the electrical signal to light and back again, the A1458 ensures that there is no physical connection between the input and output. This prevents "ground loops" and protects low-voltage microcontrollers (like an Arduino or STM32) from high-voltage transients.
