1458 Optocoupler Datasheet Jun 2026

Emitter terminal of the Channel 2 phototransistor.

Among the sea of component numbers, "1458" appears frequently in search queries and parts lists. However, there is a critical distinction to make immediately: This confusion is common. Therefore, this article serves two purposes:

High-isolation barrier between patient-side sensors and monitoring equipment. 1458 optocoupler datasheet

The 1458 optocoupler provides an efficient, space-saving solution for dual-channel electrical isolation challenges. Offering high common-mode transient immunity, predictable current transfer ratios, and a compact 8-pin footprint, it bridges the gap between basic slow-speed optocouplers and expensive high-speed digital isolators.
