ACML-7410-500E

Overview

The Broadcom ACML-7410-500E is a high-speed CMOS digital isolator utilizing magnetic coupling technology. It features four independent channels with unidirectional signal transmission. The device supports data rates up to 100 MBd and provides an isolation voltage of 5600 Vrms. It operates within a supply voltage range of 3V to 5.5V, consuming a typical operating current of 30.5 mA. Key electrical parameters include a maximum propagation delay of 32 ns and a common-mode transient immunity of 25 kV/µs. The component is housed in a 16-pin SOIC package and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Employs magnetic coupling through a thick insulation barrier for robust signal isolation.
• Provides high common-mode transient immunity to maintain signal integrity in noisy environments.
• Features low propagation delay and pulse width distortion for precise timing applications.
• Supports standard 3.3V and 5V logic levels for versatile interface compatibility.

Applications

• Isolating data conversion devices such as ADCs and DACs
• Protecting parallel buses in industrial control systems
• Peripheral interface isolation in embedded systems

Procurement Notes

Verify the specific suffix '500E' to ensure correct packaging configuration, as it typically denotes tape-and-reel or cut-tape formats compared to tube variants. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability fluctuates. Ensure the ordering part number matches the required package style and quantity format for your assembly process.

Selection Notes

Select this component when bidirectional isolation is not required, as it is strictly unidirectional. It is suitable for applications demanding high speed (100 MBd) and strong noise rejection (25 kV/µs). Consider the 16-SOIC package constraints and thermal dissipation requirements. Compare against the ACML-7400 series if bidirectional functionality or different channel counts are needed.

Part Context

This part belongs to the Broadcom ACML series of CMOS digital isolators. The series utilizes proprietary magnetic coupling technology, offering advantages over traditional optical or capacitive isolators regarding size and longevity. The ACML-7410 variant specifically provides four isolated channels, making it a compact solution for multi-channel isolation needs in space-constrained designs.

Replacement Considerations

Check for pin-compatible alternatives within the ACML-7400 family, such as the ACML-7410-000E, noting differences in packaging (tube vs. reel). Verify that any substitute maintains the same 100 MBd data rate and 5600 Vrms isolation rating to ensure system performance parity.
