ACPL-H312-560E

Overview

The ACPL-H312-560E is a high-speed logic output optocoupler manufactured by Broadcom Limited. It features a GaAsP LED coupled to an integrated circuit with a totem-pole output stage, designed for fast signal transmission across isolation barriers. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a forward current of 16 mA. Key electrical parameters include a propagation delay of 100 ns and a rise/fall time of 50 ns. It provides a common-mode transient rejection capability of 10 kV/µs and offers an isolation voltage of 5000 Vrms. The component is housed in a standard SO-6 surface-mount package.

Procurement Notes

Verify the specific ordering suffix (e.g., -560E) against the manufacturer's official datasheet to ensure correct packaging and compliance specifications. Confirm that the requested part number matches the exact pinout and electrical characteristics required for your design. Cross-reference the manufacturer's latest documentation to validate availability and any recent revisions to the product specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high-speed digital isolation between microcontrollers and power stages. Ensure the application environment stays within the specified operating temperature range and that the load requirements align with the totem-pole output drive capabilities. Consider the isolation voltage rating relative to the system's working voltage to maintain adequate safety margins during operation.

Part Context

This device belongs to the ACPL series of high-speed optocouplers from Broadcom Limited. The series is engineered for applications demanding rapid signal transfer and reliable galvanic isolation. The ACPL-H312 variant specifically targets high-performance digital isolation needs where speed and noise rejection are critical factors in maintaining system integrity.

Replacement Considerations

Consult the manufacturer's official replacement guide for verified substitute part numbers. Do not assume cross-compatibility with other logic output optocouplers without verifying pinout, electrical parameters, and isolation ratings.
