FOD617AS

Overview

The FOD617AS is a high-speed optocoupler featuring an AlGaAs LED coupled to a high-speed integrated logic gate output. It provides electrical isolation between input and output circuits while transmitting digital signals. The device operates with a supply voltage range of 4.5V to 5.5V and supports data rates up to 10 Mbps. Key electrical characteristics include a propagation delay of typically 80 ns and a pulse width distortion of 20 ns. It offers a common mode transient immunity of 10 kV/µs minimum, ensuring reliable signal transmission in noisy environments.

Feature Summary

• High-speed data transmission capability suitable for digital communication interfaces
• Integrated logic gate output simplifies circuit design by eliminating external components

Procurement Notes

Verify the specific suffix 'AS' indicates the tape and reel packaging variant when ordering. Confirm the manufacturer date code and lot traceability requirements for your production line. Ensure that the storage conditions before soldering comply with the moisture sensitivity level specified in the datasheet to prevent package damage during reflow processes.

Selection Notes

Choose this component when high-speed digital isolation is required with minimal external circuitry. The integrated logic output reduces board space and component count compared to discrete phototransistor options. Consider the operating temperature range and isolation voltage ratings to ensure compatibility with the system's electrical environment and safety standards.

Part Context

This part belongs to onsemi's family of high-speed optocouplers designed for robust signal isolation. It complements other devices in the series offering varying speed and isolation capabilities.
