ACPL-W70L-020E

Overview

The ACPL-W70L-020E is a single-channel high-speed CMOS optocoupler manufactured by Broadcom Limited. It features a push-pull totem pole output configuration capable of data rates up to 15 MBd. The device provides an isolation voltage of 5000 Vrms and exhibits a common mode transient immunity (CMTI) of 10 kV/µs. Electrical characteristics include a maximum propagation delay of 55 ns for both low-to-high and high-to-low transitions, with typical rise and fall times of 3.5 ns. The unit supports a maximum input current of 10 mA and delivers an output current of 10 mA per channel within a 6-pin Small Outline package.

Feature Summary

• High-speed digital signal transmission capability supporting data rates up to 15 MBd
• Robust noise immunity characterized by a 10 kV/µs common mode transient rejection rating
• Push-pull totem pole output architecture ensuring fast switching performance

Applications

• Industrial automation control systems requiring galvanic isolation
• Power supply feedback loops in switching regulators
• Communication interfaces demanding high-speed data transfer across isolated boundaries

Procurement Notes

Verify the specific ordering suffix to confirm the exact package variant and tape-and-reel specifications. Ensure that the selected component matches the required isolation voltage ratings and thermal management needs for the target application environment. Cross-reference the manufacturer's latest documentation to confirm compliance with current environmental standards and availability status before finalizing procurement plans.

Selection Notes

Select this component when high-speed digital isolation is required alongside strong noise immunity. The 15 MBd data rate and 10 kV/µs CMTI make it suitable for noisy industrial environments. Consider the 6-pin SSO package dimensions for PCB layout constraints. Verify that the logic output type aligns with the receiving circuit's input requirements to ensure proper signal integrity and system reliability.

Part Context

This device belongs to the ACPL-W70L series of high-speed CMOS optocouplers from Broadcom Limited. The series includes single-channel and dual-channel variants designed for applications requiring fast signal transmission across isolation barriers. The W70L family is engineered to provide reliable performance in demanding electronic systems where electrical noise and ground potential differences are significant concerns.

Replacement Considerations

Direct substitutes within the same series include the ACPL-W70L-000E and ACPL-W70L-500E. These parts share identical core electrical specifications and pin configurations but may differ in packaging or reel quantities. Verify that any replacement part maintains the same 5000 Vrms isolation rating and 15 MBd speed capability to ensure functional equivalence.
