ACPL-074L-000E

Overview

The Broadcom ACPL-074L-000E is a dual-channel high-speed CMOS optocoupler housed in an SOIC-8 package. It supports data rates up to 15 MBd with push-pull outputs. Key electrical parameters include a 3750 Vrms isolation voltage, 20 ns typical rise time, and 25 ns typical fall time. The device operates within a temperature range of -40°C to +105°C and features a common mode rejection ratio of 10 kV/µs.

Feature Summary

• Dual-channel architecture for multiplexed data transmission
• High common mode rejection ratio for noise immunity
• Push-pull output stage for fast signal switching

Applications

• Microprocessor system interface
• Multiplexed data transmission
• Industrial communication networks

Procurement Notes

Verify the specific suffix '000E' to confirm lead-free and RoHS compliance status as defined by Broadcom. Ensure the SOIC-8 package dimensions match the target PCB footprint. Confirm that the 15 MBd speed rating aligns with the system's timing requirements before finalizing procurement.

Selection Notes

Select this component when dual-channel isolation is required at high speeds. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 3750 Vrms isolation barrier for safety-critical applications requiring robust noise immunity in noisy industrial environments.

Part Context

This part belongs to the ACPL series of high-speed digital optocouplers from Broadcom. It complements single-channel variants like the ACPL-071L, offering integrated dual-channel functionality in the same compact SOIC-8 form factor. The series is designed for demanding digital isolation applications.
