1458 Optocoupler Datasheet [portable] Link

Traditional general-purpose optocouplers encounter a bottleneck: the large base-collector capacitance of standard phototransistors slows down signal transitions, resulting in prolonged propagation delays.

: While the keyword "1458 optocoupler" is used, the specific devices referred to are the HCPL-1458 and HCNW1458 manufactured by Broadcom (formerly Avago Technologies and Agilent). When you see "1458" in the context of an optocoupler, this is the family it belongs to.

, are designed with clock inputs that allow for a for better isolation. 1458 optocoupler datasheet

is a premier single-channel, high-speed optocoupler designed for robust signal isolation in modern, low-voltage electronic systems . Manufactured by Avago Technologies (now Broadcom/Avago), this component is engineered to provide high-speed data transmission while maintaining high common-mode transient immunity (CMR), making it an ideal choice for digital logic ground isolation, industrial control, and communication interfaces.

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. , are designed with clock inputs that allow

: High-speed logic ground isolation (TTL/CMOS compatible).
