ACPL-H312-000E

Overview

The ACPL-H312-000E is a single-channel logic output optocoupler manufactured by Broadcom Limited. It features an 8-pin SOIC surface-mount package with rail-to-rail output capability. The device provides 3.75 kVrms isolation voltage and supports DC input current up to 16 mA. Typical switching performance includes a rise time of 0.05 µs and a fall time of 0.05 µs. The maximum forward voltage is specified at 1.8 V, ensuring efficient LED drive characteristics within the component.

Feature Summary

• Rail-to-rail logic output configuration for direct interface with digital circuits
• High-speed switching performance with 0.05 µs typical rise and fall times
• Robust electrical isolation rated at 3.75 kVrms between input and output channels

Applications

• Gate drive isolation in motor control systems
• Signal isolation in industrial automation controllers
• Power supply feedback loop isolation

Procurement Notes

Verify the specific ordering suffix matches the required package type and lead-free status. Confirm that the 8-pin SOIC footprint aligns with the target PCB design constraints. Ensure the procurement channel sources genuine Broadcom Limited components to guarantee the specified 3.75 kVrms isolation rating and switching speed parameters are met without compromise.

Selection Notes

Select this component when high-speed digital signal transmission across an isolation barrier is required. The rail-to-rail output allows compatibility with standard logic families. Consider the 8-pin SOIC package for surface-mount assembly efficiency. Validate that the 16 mA maximum input current fits within the driving circuit capabilities and that the 3.75 kVrms isolation meets the safety requirements of the application environment.
