ACPL-077L-560E

Overview

The ACPL-077L-560E is a single-channel high-speed CMOS optocoupler manufactured by Broadcom Limited. It features a push-pull, totem-pole logic output capable of driving loads with up to 10 mA current per channel. The device supports data rates of 25 MBd and exhibits typical rise and fall times of 4 ns and 3 ns, respectively. Maximum propagation delay is specified at 40 ns for both low-to-high and high-to-low transitions. It operates with supply voltages of 3V to 3.6V or 4.5V to 5.5V and provides an isolation voltage of 3750 Vrms.

Feature Summary

• High common-mode transient immunity of 35 kV/µs minimizes noise susceptibility in electrically noisy environments.
• Push-pull totem-pole output architecture enables direct interfacing with digital logic circuits without external pull-up resistors.
• CMOS technology ensures low power consumption while maintaining high-speed signal transmission capabilities.

Applications

• Industrial networking systems requiring electrical isolation between diverse voltage levels.
• Data communication interfaces demanding high-speed signal integrity and noise immunity.
• Digital isolation in microcontroller-based control systems.

Procurement Notes

Verify the specific suffix (560E) corresponds to the required tape and reel packaging configuration. Confirm that the operating temperature range and supply voltage requirements align with the target system design. Ensure compliance with relevant safety certifications such as UL, CSA, and IEC standards for the intended application environment.

Selection Notes

Select this component when high-speed data transmission up to 25 MBd is required alongside robust noise immunity. The push-pull output simplifies circuit design by eliminating the need for external pull-up components. Consider the 3750 Vrms isolation rating for applications involving significant potential differences between input and output grounds.

Part Context

This part belongs to the ACPL-077L series of low-power, high-speed CMOS optocouplers. The series is designed for applications requiring fast switching speeds and low power dissipation. The 8-SO Tall package provides a compact footprint suitable for surface-mount assembly in space-constrained electronic devices.

Replacement Considerations

Check datasheets for alternative single-channel high-speed optocouplers with compatible 25 MBd data rates and 3750 Vrms isolation. Verify pinout compatibility and output drive strength before substitution. Ensure equivalent common-mode transient immunity specifications are met.
