ACPL-024L-500E

Overview

The ACPL-024L-500E is a high-speed, dual-channel digital optocoupler manufactured by Broadcom Limited. It features a CMOS output stage and operates at data rates up to 5 Mb/s. The device provides 3750 Vrms isolation voltage and supports a wide operating temperature range from -40°C to +105°C. Packaged in an 8-pin SOIC format, it utilizes a low-power design with a typical forward current of 2.2 mA and forward voltage of 1.5 V. Key timing parameters include rise and fall times of 11 ns each.

Feature Summary

• Dual-channel configuration with CMOS logic output stages for reliable digital signal transmission
• High common-mode transient immunity (CMTI) of 25 kV/µs for noise-resistant performance
• Low power consumption design suitable for energy-efficient industrial applications

Applications

• Industrial automation control systems
• Communication equipment signal isolation
• Power supply feedback loops

Procurement Notes

Verify the specific suffix '500E' corresponds to the reel packaging quantity and RoHS compliance status required for your assembly line. Confirm that the 8-pin SOIC tall package dimensions match your PCB footprint constraints. Ensure the 3750 Vrms isolation rating meets the safety standards of your target application environment before finalizing procurement.

Selection Notes

Select this component when dual-channel isolation is required alongside high-speed data transmission capabilities. The CMOS output structure offers lower propagation delay compared to phototransistor alternatives. Consider the 2.2 mA drive current requirement for interface compatibility with your microcontroller or logic source. The wide temperature range makes it suitable for harsh industrial environments.

Part Context

This part belongs to the ACPL-x2xL series of low-power digital optocouplers. It represents an evolution in industrial-grade isolation technology, combining speed with power efficiency. The series is designed to replace older discrete solutions, offering integrated dual channels in a compact surface-mount package for space-constrained designs.

Replacement Considerations

Direct substitutes within the same family include ACPL-024L-000E, which shares identical electrical characteristics but differs in packaging type. Verify pinout compatibility and isolation voltage ratings when considering cross-references from other manufacturers.
