The search for a is a classic case of part number confusion. While the 1458 is a legendary dual op-amp, no mainstream optocoupler bears that exact label. However, by understanding the anatomy of a standard optocoupler datasheet (CTR, VISO, timing, and pinout) as exemplified by the 4N35 or PC817, you can effectively use any general-purpose optoisolator you encounter.
3.0V to 5.5V, offering flexibility for both 3.3V and 5V logic systems. Propagation Delay: 1458 optocoupler datasheet
A datasheet will show CTR graphs. For a generic optocoupler, CTR decreases as temperature rises and as the optocoupler ages (over years). For reliable digital communication, ensure your IC is at least 2x the required input current of your receiving chip. The search for a is a classic case of part number confusion
