ACML-7400-500E

Overview

The Broadcom ACML-7400-500E is a multi-channel, high-speed CMOS digital isolator utilizing magnetic coupling through a thick insulation barrier. It features four forward channels and zero reverse channels, supporting data rates up to 100 MBd with a maximum propagation delay of 27 ns. The device offers an isolation voltage of 5600 Vrms and a common-mode transient immunity (CMTI) of 25 kV/µs. Operating supply current is specified at 40 mA, with pulse width distortion maximized at 2 ns. It functions within a temperature range of -40°C to +125°C and is housed in a 16-SOIC package.

Feature Summary

• Utilizes magnetic coupling technology through a thick insulation barrier for signal transmission
• Provides uni-directional data isolation suitable for parallel buses and peripheral connections
• Features high common-mode transient immunity to maintain signal integrity in noisy environments

Applications

• Isolating data conversion devices
• Parallel bus isolation
• Peripheral interface isolation

Procurement Notes

Verify the specific suffix '500E' against official Broadcom documentation to confirm compliance with RoHS3 standards and lead-free specifications. Ensure the 16-SOIC package dimensions match the design footprint requirements. Cross-reference the operating temperature range limits with system thermal constraints before finalizing procurement orders.

Selection Notes

Select this component when unidirectional isolation is required for high-speed digital signals up to 100 MBd. The 5600 Vrms isolation rating supports applications demanding robust galvanic separation. Consider the 16-SOIC package size for surface-mount assembly compatibility. Verify that the 40 mA supply current fits within the system power budget constraints.
