ACPL-772L-360E

Overview

The ACPL-772L-360E is a high-speed logic output optocoupler manufactured by Broadcom Limited. It features a single channel with push-pull totem pole outputs, providing galvanic isolation between input and output circuits. The device supports data rates up to 25 Mb/s with propagation delays of 6 ns typical. Key electrical parameters include an isolation voltage of 3750 Vrms and a common mode transient immunity of 10 kV/µs. It operates within a temperature range of -40°C to +85°C and dissipates up to 150 mW. The component is housed in an 8-pin surface-mount gull-wing package.

Feature Summary

• High-speed signal transmission capability supporting 25 Mb/s data rates
• Robust galvanic isolation with 3750 Vrms insulation voltage rating
• Push-pull totem pole output configuration for direct logic interfacing
• High common mode transient immunity of 10 kV/µs

Applications

• Industrial automation control systems requiring fast signal isolation
• Power supply feedback loops in switching regulators
• Data communication interfaces needing high noise immunity
• Motor drive control circuits for precise timing signals

Procurement Notes

Verify the specific suffix '360E' corresponds to the surface-mount gull-wing package variant. Confirm RoHS compliance status through official documentation as environmental declarations may vary by production batch. Ensure the ordering part number matches the required lead-free specifications. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential design changes affecting pinout or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when high-speed digital isolation is required alongside robust noise immunity. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design compared to open-collector alternatives. Consider the 3750 Vrms isolation barrier for applications demanding significant potential difference separation. Evaluate the 10 kV/µs CMTI rating against the noise environment of the target application to ensure reliable operation without false triggering.

Part Context

This device belongs to the ACPL-772L series of high-speed optocouplers from Broadcom. The series is designed for applications requiring fast response times and high reliability. The 'L' designation typically indicates logic output functionality. This specific model integrates an LED input with a dual phototransistor output stage configured for totem pole operation, distinguishing it from standard transistor-output variants in the broader optocoupler family.
