ACPL-C784-000E

ACPL-C784-000E is a single-channel optically isolated digital isolator (from Broadcom/Avago). It transfers a digital signal across a galvanic isolation barrier by using an input LED and a photodetector with a built‑in logic receiver, delivering a TTL/CMOS‑compatible output. The device is designed to isolate microcontroller or logic interfaces from high‑voltage or noisy sections in power converters, motor drives, and industrial controls. Key points:
- 1-channel isolated logic gate with standard output (TTL/CMOS compatible)
- Internal LED–photodetector with robust isolation between input and output
- Suitable for 3.3 V or 5 V output-side supplies
- Typical applications: MCU interfaces, isolated sensors and data links, and digital isolation in power and motor control
- Available in common packages (e.g., SO‑8, DIP‑8)
For exact electrical specs (input current, CTR, VISO, propagation delay, and operating conditions), refer to the ACPL-C784-000E datasheet.

Equivalent parts are other high-speed optocouplers with the same pinout/specs. The main cross is the Avago/Broadcom HCPL-C784-000E (or HCPL-C784 family); ACPL-C784-000E is typically the same device under another prefix. For exact cross-references, specify isolation voltage, CTR and speed, or use DigiKey/Mouser cross-reference tools.
