概要

Description

HCPL-4534-500E is a single‑channel, high‑speed optocoupler (Broadcom/Avago HCPL‑4534 family). It provides galvanic isolation between the LED input and the output circuitry, enabling fast, noise‑resistant signal transfer across voltage domains. The “-500E” suffix denotes the reinforced isolation (around 5 kV RMS) with industrial/extended temperature performance. The device combines an LED input and an integrated photodetector/amplifier to deliver a TTL/CMOS‑compatible output, suitable for isolated interfaces in power supplies, motor drives, and microcontroller systems. Typical features include low input current drive, fast propagation delay, and good common‑mode transient immunity. The output side is powered by a 4.5–5.5 V supply, while the input LED is driven by a small forward current. Packages are 8‑pin DIP or SOIC. Applications: isolating controllers from high‑voltage/high‑power sections, safety‑critical signal isolation, EMI/ground‑loop reduction.

Features

- High-speed optocoupler with logic-gate output (TTL/CMOS compatible)
- 5 kV RMS reinforced isolation between input and output
- Push-pull (totem-pole) output for easy interfacing
- High common-mode transient immunity for noisy environments
- Industrial temperature range (-40°C to +125°C)
- Output supply: typically 3.3–5.5 V
- Pb-free, RoHS compliant; UL 1577 safety rating
- Available in compact 8-pin packages (DIP8/SOIC8)
Ideal for isolated data paths in power, motor drive, and telecom applications.

Package

8-pin SO-8 surface-mount package; the -E suffix indicates Pb-free.

Pinout

- Pin count: 16 pins (DIP; available in other packages)
- Function: Quad-channel optically isolated digital isolator. Each channel has an input LED on the primary (input) side and an isolated output on the secondary (output) side, providing four isolated logic signals with separate Vcc2 and GND2.

Manufacturer

Manufacturer: Broadcom Inc. (formerly Avago Technologies).
What kind of company: A global semiconductor company that designs and manufactures analog, digital, and mixed-signal ICs and optoelectronic devices, including optocouplers like the HCPL-4534-500E.

Application

- Isolated digital interfaces for microcontrollers/PLCs
- Gate-drive isolation for MOSFET/IGBTs in SMPS and motor drives
- Isolated data links and remote I/O in industrial systems
- High‑reliability telecom and medical instrumentation needing strong isolation
- Isolated measurement/feedback in power converters and power supplies

Equivalent

Direct equivalents are vendor-specific. The HCPL-4534-500E is the Broadcom/Avago 4‑channel high‑speed optocoupler with 5 kV isolation. The closest cross-reference is ACPL-4534-500E (the same device family). Other suppliers’ equivalents exist only within their own 4‑channel, 5 kV isolation optocoupler lines; for precise cross-references, check distributor search (Digi‑Key/Mouser) or a cross-reference database.
