OLS300

Overview

The OLS300 is a high-speed optocoupler manufactured by Skyworks Solutions, Inc. It features hermetic surface-mount construction with an electrical isolation rating of 1,500 VDC between input and output circuits. The device integrates an LED emitter and a photodiode transistor detector to achieve enhanced switching speeds compared to standard phototransistors by minimizing base-collector capacitance. Designed for robust signal transmission in electrically noisy environments, it supports applications requiring precise control and isolation for high-voltage DC systems.

Feature Summary

• Hermetic surface-mount packaging ensures durability and reliability in demanding environments
• High-speed switching capability achieved through reduced base-collector capacitance in the photodiode transistor detector
• Provides 1,500 VDC electrical isolation between input and output channels

Applications

• Interface between transistor-transistor logic (TTL) and low-power Schottky transistor-transistor logic (LSTTL)
• CMOS and broadband analogue applications
• High-speed digital interfaces requiring ground loop elimination
• Input and output buffering in high-voltage DC systems

Procurement Notes

Verify the specific datasheet version and package configuration when sourcing. Confirm that the hermetic seal requirements align with your environmental specifications. Ensure compatibility with TTL, LSTTL, or CMOS logic families as intended. Check for any specific handling instructions related to the surface-mount technology. Validate the isolation voltage ratings against system safety standards before integration.

Selection Notes

Select this component when high-speed signal transmission is required alongside significant electrical isolation. The hermetic construction makes it suitable for harsh environments where standard plastic packages may fail. Consider its compatibility with TTL and LSTTL logic levels if interfacing legacy systems. The reduced capacitance design benefits applications sensitive to switching delays. Evaluate the 1,500 VDC isolation rating against the maximum voltage differences in your circuit design.
