Product Overview

The TT electronics OPI1266 is a high-voltage isolator designed to provide maximum DC and AC current isolation between input and output while maintaining TTL/LSTTL circuit compatibility. It features a GaAIAs LED coupled with an integrated circuit detector, including a photodiode, a high-gain linear amplifier, and a Schottky clamped open collector output transistor. The circuit is temperature, current, and voltage compensated, with matched propagation delay times over the entire temperature range for precise timing. This isolator is suitable for data transmission in high-voltage isolation applications, PC board power system isolation, industrial equipment power isolation, medical equipment power isolation, and office equipment power isolation.
