1458 Optocoupler Datasheet — Summary Report

Overview

The "1458" optocoupler (assumed common through-hole transistor-output optocoupler family; e.g., generic PC817-like single-channel phototransistor optocoupler) provides electrical isolation between input (LED) and output (phototransistor). Typical use cases: microcontroller isolation, signal level shifting, noise suppression, and protecting low-voltage logic from high-voltage circuits.

• Rise time: 4µs
• Fall time: 5µs

Telecommunications: High-speed digital signal switching and line receivers. 1458 optocoupler datasheet

Introduction

Be careful not to confuse the HCPL-1458 with the LM1458 or MC1458. While they share the "1458" number, the LM1458 is a Dual Operational Amplifier and does not provide optical isolation. 1458 Optocoupler Datasheet — Summary Report Overview The
