ACPL-K73L-500E

Overview

The ACPL-K73L-500E is a dual-channel high-speed CMOS optocoupler featuring push-pull logic outputs. It operates with a supply voltage range of 3V to 3.6V and 4.5V to 5.5V, supporting a data rate of 15MBd. The device provides an isolation voltage of 5000Vrms and a common-mode transient immunity of 10kV/µs. Maximum propagation delays are 55ns for both low-to-high and high-to-low transitions. It utilizes an 8-pin SOIC stretched package and is designed for applications requiring robust signal isolation.

Feature Summary

• High-speed data transmission capability up to 15MBd using advanced CMOS technology
• Robust noise immunity with 10kV/µs common-mode transient rejection
• Push-pull output stage design ensuring strong drive capability
• Wide operating temperature range suitable for demanding industrial environments

Applications

• Industrial automation control systems
• Data communication interface isolation
• Power supply feedback loops
• Signal isolation in noisy electrical environments

Procurement Notes

Verify the specific suffix '500E' against official Broadcom documentation to confirm the tape-and-reel packaging variant, as suffixes often dictate shipping format rather than electrical function. Ensure compatibility with 3V and 5V logic levels. Confirm RoHS compliance status through current manufacturer declarations. Cross-reference pinout diagrams with target PCB layout requirements before integration.

Selection Notes

Select this component when high-speed digital isolation is required between circuits with significant ground potential differences. The push-pull output architecture offers superior performance over open-collector types for driving capacitive loads. Consider the 10kV/µs CMTI rating for environments with rapid voltage transients. Evaluate power consumption constraints given the CMOS input characteristics.

Part Context

This device belongs to the ACPL-K73L series of high-speed CMOS optocouplers from Broadcom Limited. The series is engineered to provide reliable galvanic isolation while maintaining high data integrity. The dual-channel configuration allows for simultaneous signal transmission across isolated boundaries, making it suitable for complex digital interfaces where space efficiency and speed are critical design parameters.

Replacement Considerations
