概述

Description

EL4581CSZ is a high‑speed optically isolated coupler (photocoupler) from Everlight. It provides galvanic isolation between input and output, so a low‑voltage control side can safely drive a high‑voltage/noisy side without a direct electrical connection.
- Function: transfers a digital signal across an isolation barrier (input LED side to output transistor/logic side).
- Packaging: CSZ denotes a specific 8-pin package variant and related tape/reel packaging.
- Typical use: digital signal isolation in microcontroller interfaces, motor drives, power supplies, and data links.
- Key specs to check in the datasheet: input LED current, current transfer ratio (CTR), isolation voltage (Viso), and output type (transistor/open‑collector or logic-compatible).
If you need exact electrical characteristics or packaging details, consult the EL4581CSZ datasheet from Everlight.

Package

8-pin surface-mount SOP (SO-8) package; RoHS-compliant.

Pinout

- Pin count: 8 pins
- Function: Dual-channel optocoupler (photocoupler) in an SO-8 package; provides galvanic isolation between input LEDs and output transistors (two isolated channels, typically with transistor outputs).

Manufacturer

- Manufacturer: Everlight Electronics Co., Ltd. (Everlight)
- What kind of company: A Taiwanese multinational electronics company that designs and manufactures optoelectronic components (e.g., optocouplers, LEDs, infrared components) and related electronics for consumer, automotive, and industrial markets.

Application

EL4581CSZ is a single-channel optically isolated device (digital isolator/isolated amplifier) for transferring signals across an isolation barrier. Common applications:
- Industrial control/automation (isolated I/O, gate drive, PLC interfaces)
- Switch-mode power supplies (SMPS feedback isolation)
- Data acquisition/instrumentation (sensor isolation, noise immunity)
- Medical equipment (patient-safe isolation)
- Automotive/transport electronics
- Communications equipment needing galvanic isolation
