ACSL-7210-50RE

Overview

The Broadcom ACSL-7210-50RE is a high-speed, dual-channel logic output optocoupler housed in an 8-SOIC surface-mount package. It features a push-pull output configuration with a data rate of 25 MBd and isolation voltage of 3750 Vrms. Key electrical parameters include a maximum propagation delay of 40 ns for both rise and fall transitions, typical rise/fall times of 5.1 ns/3.8 ns, and a minimum common-mode transient immunity of 25 kV/µs. The device supports supply voltages of 3V–3.6V or 4.5V–5.5V, operates within a -40°C to 105°C temperature range, and provides 10 mA output current per channel.

Feature Summary

• High-speed digital signal transmission capability at 25 MBd
• Robust noise immunity with 25 kV/µs common-mode transient rejection
• Push-pull output stage ensures strong drive capability and fast switching
• Wide operating temperature range suitable for industrial environments

Applications

• Industrial automation control systems
• Data communication interface circuits
• Isolated logic signal transmission
• Power supply feedback loops

Procurement Notes

Verify the specific suffix '50RE' corresponds to the required RoHS compliance and tape-and-reel packaging format. Confirm that the 8-SOIC footprint matches the target PCB design constraints. Ensure the selected component meets the necessary insulation voltage ratings for the intended application safety standards. Cross-reference the manufacturer's latest datasheet revision to confirm active status and any potential form-fit-function changes.

Selection Notes

Select this component when high-speed data integrity and strong noise immunity are critical requirements. The push-pull output architecture is preferred over open-collector types for applications demanding faster edge rates and bidirectional drive strength. Consider the 3750 Vrms isolation barrier for safety-critical interfaces between low-voltage logic and higher-voltage power stages. Evaluate thermal performance within the specified -40°C to 105°C operational window.

Part Context

This part belongs to the Broadcom ACSL-7210 series of high-speed optocouplers. It is designed as a successor or alternative to older logic-output isolators, offering significantly improved speed and noise immunity. The series utilizes advanced LED and photodiode technology to achieve high CMTI while maintaining compact surface-mount packaging for modern electronic assemblies.

Replacement Considerations

Direct replacements may include other 25 MBd dual-channel push-pull optocouplers with similar 3750 Vrms isolation. Verify pinout compatibility and electrical parameter margins before substitution. Check for equivalent common-mode transient immunity ratings to ensure noise performance is maintained.
