ACPL-024L-000E

Overview

The ACPL-024L-000E is a dual-channel high-speed digital optocoupler manufactured by Broadcom Limited. It features a CMOS output stage and optical receiver input stages with built-in Schmitt triggers, designed for low power applications. The device operates at data rates up to 5 Mb/s and provides an insulation voltage of 3750 Vrms. It supports a forward current of 2.2 mA with a typical forward voltage of 1.5 V. The component exhibits rise and fall times of 11 ns each, ensuring rapid signal transmission. It is housed in an SOIC-8 through-hole package and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Dual-channel architecture with integrated Schmitt trigger inputs for noise immunity
• CMOS output stage optimized for low power consumption
• High common-mode transient immunity of 25 kV/µs

Applications

• Industrial communication bus interfaces
• Ground isolation in noisy environments
• Signal coupling between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix '000E' corresponds to the lead-free and halogen-free compliant version as indicated by RoHS details. Confirm that the SOIC-8 through-hole mounting style matches the PCB footprint requirements. Ensure the 5 Mb/s data rate specification aligns with the system's timing constraints. Cross-reference the 3750 Vrms isolation rating against safety standards required for the target application environment.

Selection Notes

Select this component when dual-channel isolation with low power consumption is required. The CMOS output stage offers better compatibility with digital logic families compared to transistor outputs. The high CMTI rating makes it suitable for systems with significant electrical noise. Consider the 11 ns switching speed for applications requiring moderate data throughput without excessive propagation delay.
