ACPL-061L-500E

Overview

The ACPL-061L-500E is a high-speed, single-channel digital CMOS optocoupler manufactured by Broadcom Limited. It features a tri-state logic output and provides electrical isolation with a rated insulation voltage of 3750 Vrms. The device supports data rates up to 10 MBd and exhibits a common-mode transient immunity (CMTI) of 20 kV/µs. It operates within an extended temperature range from -40°C to +105°C and is housed in an 8-pin SOIC package.

Feature Summary

• Ultra-low power consumption with maximum supply current of 1.5 mA across the operating temperature range
• High-speed digital interface capability supporting data rates up to 10 MBd
• Robust noise immunity characterized by a common-mode transient immunity of 20 kV/µs
• Tri-state logic output configuration for flexible system integration

Applications

• RS485 communication interfaces
• CAN Bus systems
• I2C bus isolation
• Microprocessor system interfaces

Procurement Notes

Verify the specific suffix '500E' to confirm RoHS compliance and lead-free status as per Broadcom specifications. Ensure the ordering part number matches the required packaging format, such as tape and reel or cut tape, to align with assembly requirements. Cross-reference the datasheet for any recent updates regarding pinout or thermal characteristics before finalizing procurement.

Selection Notes

Select this component when low power dissipation is critical alongside high-speed signal transmission. The tri-state output allows multiple devices to share a bus without external pull-up resistors in some configurations. Verify that the required isolation voltage meets the application's safety standards, as this device offers 3750 Vrms isolation suitable for general industrial and commercial environments.

Part Context

This device belongs to the ACPL series of high-speed optocouplers from Broadcom Limited. It is designed to replace older HCPL-061L variants while offering improved power efficiency and performance metrics. The series is widely used in industrial automation and communication equipment requiring reliable galvanic isolation between digital circuits.

Replacement Considerations

The HCPL-061L-500E is a direct predecessor in the same family. When substituting, verify that the legacy part's lower CMTI rating does not compromise system integrity in noisy environments. Ensure pin compatibility remains consistent between the HCPL and ACPL series for the same logical function.
