ACPL-P480-000E

Overview

The Broadcom ACPL-P480-000E is a high-speed, single-channel logic output optocoupler featuring an AlGaAs LED input and a Schmitt trigger photo detector. It provides a 3750 Vrms isolation voltage with a 20 kV/µs common-mode transient immunity rating. The device operates within a supply voltage range of 4.5V to 20V and supports a maximum forward current of 10 mA. Typical propagation delays are 350 ns for both rise and fall transitions. It functions in temperatures from -40°C to +100°C and utilizes a 6-pin SOIC surface-mount package.

Feature Summary

• Integrates a Schmitt trigger at the output stage to eliminate noise susceptibility and ensure clean digital signal transmission.
• Delivers high common-mode transient immunity of 20 kV/µs for reliable operation in electrically noisy environments.
• Features a push-pull totem pole output configuration capable of sourcing and sinking up to 25 mA.

Applications

• Gate drive interface circuits for intelligent power modules
• Signal isolation in industrial automation control systems
• Communication interfaces requiring high noise immunity

Procurement Notes

Verify the specific ordering suffix against official Broadcom documentation to confirm pinout compatibility and packaging type. Ensure that the selected variant matches the required isolation voltage ratings and operating temperature ranges for the target application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when high-speed digital isolation is required alongside robust noise rejection capabilities. The integrated Schmitt trigger makes it suitable for applications where signal integrity is critical in high-interference settings. Consider the 20 kV/µs CMTI rating for proximity to switching loads. Evaluate the 350 ns propagation delay against system timing requirements to ensure adequate response speeds for the intended data rates.
