Overview
The ACPL-074L-500E is a dual-channel high-speed digital optocoupler manufactured by Broadcom Limited. It features a CMOS input LED paired with a push-pull output stage, enabling data rates up to 15 Mb/s. The device provides an isolation voltage of 3750 Vrms and supports a wide operating temperature range from -40°C to +105°C. Packaged in an 8-pin SOIC surface-mount format, it offers low propagation delay and high common-mode transient immunity for reliable signal transmission across isolated boundaries.
Feature Summary
- Dual-channel architecture supporting independent signal isolation
- Push-pull output stage for fast switching and strong drive capability
- High common-mode transient immunity for noise-resistant operation
- CMOS-compatible input interface for direct logic connection
Applications
- Industrial communication bus isolation
- Power supply feedback loops
- Gate driver isolation for power electronics
- Digital isolator replacement in legacy designs
Procurement Notes
Verify the specific suffix '500E' to confirm tape-and-reel packaging and lead-free compliance. Ensure the order matches the dual-channel variant, as single-channel versions exist within the same family. Cross-reference the manufacturer part number with official datasheets to avoid confusion with similar ACPL-074 series components that may differ in channel count or output type.
Selection Notes
Select this component when dual-channel isolation at 15 Mb/s is required. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 8-pin SOIC package constraints for PCB layout. Verify that the 3750 Vrms isolation rating meets the safety requirements of the target application environment.
Part Context
This part belongs to the ACPL-074L series of high-speed CMOS optocouplers. The series includes both single-channel and dual-channel variants with identical electrical characteristics but different pin configurations. The ACPL-074L-500E specifically denotes the dual-channel version with standard industrial packaging options.
Replacement Considerations
ACPL-074L-000E is a tube-packaged alternative with identical electrical specifications. Single-channel equivalents include ACPL-072L-500E. Verify pin compatibility before substitution, as channel count differences affect footprint requirements.
