ACML-7400-000E

Overview

The Broadcom ACML-7400-000E is a multi-channel, high-speed CMOS digital isolator utilizing magnetic coupling through a thick insulation barrier. It features four independent channels with unidirectional signal transmission and a data rate of 100 Mb/s. The device operates on a supply voltage between 3 V and 5.5 V, drawing a typical operating current of 30.5 mA. It provides an isolation voltage of 5600 Vrms and exhibits a propagation delay of 27 ns. The component supports a wide operating temperature range from -40°C to +105°C and is housed in a 16-pin SOIC-Narrow package.

Feature Summary

• Employs magnetic coupling technology for high-speed signal transmission across a thick insulation barrier
• Provides four independent unidirectional channels for efficient multi-line isolation
• Delivers high common-mode transient immunity to ensure reliable operation in noisy environments

Applications

• Industrial automation systems requiring robust galvanic isolation
• Medical equipment needing certified safety isolation barriers
• Power electronics interfaces for motor control and inverters

Procurement Notes

Verify the specific suffix code against official Broadcom documentation to confirm pinout and electrical characteristics. Ensure the procurement source provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor listings to avoid counterfeit components. Confirm packaging type matches project requirements before finalizing orders.

Selection Notes

Select this component when four isolated channels are required within a single package footprint. Consider the 100 Mb/s data rate limit for signal integrity analysis. Evaluate the 5600 Vrms isolation rating against system safety standards. Compare power consumption metrics with alternative technologies if thermal management is critical.

Part Context

This device belongs to the Broadcom ACML series of digital isolators. It shares architectural similarities with the ACML-7410 and ACML-7420 models, differing primarily in package width and channel configuration. The series represents a shift from traditional optical isolation to magnetic coupling for improved speed and reliability.

Replacement Considerations

Official substitutes include the ACML-7410-000E and ACML-7420-000E. Verify package dimensions and pin compatibility before substitution. Ensure equivalent isolation voltage and data rate specifications are maintained.
