ISP827-2

Overview

The ISP827-2 is a high-density phototransistor optically coupled isolator manufactured by Isocom Components. It features a dual-channel configuration with separate inputs and outputs, providing robust signal isolation in compact packages. The device is designed for applications requiring reliable data transmission across isolated circuits, offering high current transfer ratios and fast switching speeds suitable for digital logic interfaces.

Feature Summary

• Dual-channel architecture for independent signal isolation
• High current transfer ratio for efficient logic interfacing
• Hermetically sealed ceramic construction for reliability
• Compatible with standard DIP and flat pack mounting styles

Applications

• Logic-to-logic isolation in noisy environments
• Line receiver circuits
• Programmable current level sensors
• Computer and peripheral device interfaces

Procurement Notes

Verify the specific suffix (e.g., BLXG) against your bill of materials, as Isocom uses suffixes to denote lead forms and approval statuses such as UL or VDE recognition. Confirm package type requirements, as the base part number may correspond to multiple physical configurations including plastic DIP or hermetic ceramic variants. Ensure environmental compliance certifications match your project specifications.

Selection Notes

Select this component when high density and dual-channel isolation are required within a single package. Consider the operating temperature range and insulation voltage ratings relative to your circuit's safety standards. Evaluate the current transfer ratio requirements to ensure adequate noise immunity and signal integrity for your specific logic family interface needs.

Part Context

This part belongs to Isocom's high-density phototransistor optocoupler series, which serves as a direct replacement for legacy components from manufacturers like Toshiba and Sharp. The series emphasizes miniaturization and reliability, catering to industries demanding compact solutions for power supply control and industrial automation systems.

Replacement Considerations

Direct replacements include TLP621, SFH615A, and ISP817 variants depending on the specific channel count and package style. Verify pinout compatibility and electrical parameters before substitution to ensure seamless integration into existing designs without circuit modification.
