Broadcom AC/DC Input 2-Channel Optocoupler, Surface, 8-Pin SO

Broadcom ACPL Series Optocoupler, 3750Vrms Isolation Voltage, 105°C Maximum Operating Temperature - ACPL-064L-500E

This optocoupler provides galvanic separation between input and output stages for signal isolation in electronic systems. It is designed for surface mounting and supports AC and DC drive conditions while operating across an extended ambient temperature range, making it suitable for industrial circuit isolation where compact, dual‑channel signal transfer is required.

Features and Benefits:

• 3750Vrms isolation ensures high‑voltage separation for safety
  Dual‑channel SO package enables two isolated signal paths
  20%-400% current transfer ratio offers a wide signal gain range
  6mA maximum input current minimises drive requirements
  12ns rise and fall times deliver Rapid signal switching
  −40 to 105°C operating range supports harsh environments

Applications

• Used for isolating control signals in power supplies
  Suitable for interfacing microcontrollers with high‑voltage circuits
  Ideal for sensor signal isolation in industrial automation
  Can be used for switching logic in dual‑channel designs
  Used with mixed AC/DC input systems requiring separation

What standards does it meet for safety and regulatory acceptance?

It conforms to IEC/EN/DIN EN 60747‑5‑5 and UL 1577 and is covered by CSA and RoHS approvals.

How many pins and channels are available for PCB implementation?

It uses an eight‑pin SO package and provides two independent channels.

What are the electrical limits for LED drive and output behaviour?

The forward voltage does not exceed 1.7V and the input current is capped at 6mA while the CTR ranges from 20% to 400%.

What kind of output logic compatibility can be expected?

The device provides a logic‑compatible output suitable for digital interfacing.

Is this component suitable for automotive‑grade applications?

It is not certified to automotive standards and therefore not intended for automotive use.
