ACPL-4800-300E

Overview

The ACPL-4800-300E is a single-channel logic output optocoupler manufactured by Broadcom Limited. It features an AlGaAs LED input and a Schmitt trigger output stage, designed for high-speed digital isolation. The device operates within a supply voltage range of 4.5V to 20V. Key electrical parameters include a maximum propagation delay of 350ns, with typical rise and fall times of 16ns and 20ns respectively. It provides an insulation voltage of 3750 Vrms and supports data rates up to 5 MBps. The component is housed in an 8-pin DIP package and functions within a temperature range of -40°C to +100°C.

Feature Summary

• Integrates a Schmitt trigger at the output to eliminate signal noise and ensure clean logic transitions.
• Provides high-speed digital isolation suitable for applications requiring fast data transmission rates.
• Features robust insulation capabilities with a high dielectric strength between input and output circuits.

Applications

• High-speed data communication interfaces
• Industrial control systems requiring galvanic isolation
• Logic level shifting between different voltage domains

Procurement Notes

Verify the specific suffix '300E' to confirm the tube packaging format, as other suffixes may indicate reel packaging. Ensure the procurement documentation explicitly states the 8-pin DIP configuration and the 3750 Vrms isolation rating. Cross-reference the manufacturer part number with official Broadcom datasheets to confirm the Schmitt trigger functionality and operating temperature range specifications.

Selection Notes

Select this component when a single channel of high-speed isolation with noise immunity is required. The integrated Schmitt trigger makes it suitable for noisy environments where standard logic outputs might fail. Consider the 4.5V to 20V supply range compatibility with the target system logic levels. Verify that the 350ns propagation delay meets the timing requirements of the application.

Part Context

This part belongs to the ACPL-4800 series of high-speed optocouplers from Broadcom. The series utilizes AlGaAs LED technology combined with advanced photodetector and Schmitt trigger circuitry. This design philosophy focuses on providing reliable, fast, and noise-resistant isolation for modern digital electronics, distinguishing it from slower or lower-isolation general-purpose optocouplers.
