光耦选型要看哪些参数？Which parameters matter when selecting an optocoupler?
光电耦合器选型主要看五项：Five parameters deserve close attention when selecting an optocoupler:
- 电流传输比 CTR——决定 LED 驱动电流与光敏管输出电流的比值；Current transfer ratio CTR — determines the ratio of LED drive current to phototransistor output current;
- 隔离耐压 VISO——决定能否满足系统的电气隔离要求；Isolation voltage VISO — determines whether the isolation requirement of the system is met;
- 传输延迟与上升、下降时间 tp / tr / tf——决定开关速度，数字通信与 PWM 场景尤其关键；Propagation delay and rise/fall times tp / tr / tf — determine switching speed, which is especially critical in digital communication and PWM applications;
- 输出结构——晶体管输出、达林顿输出、光继电器 PhotoMOS、可控硅输出、IGBT 与 MOSFET 栅极驱动等，决定负载驱动方式与所需驱动电流；Output structure — transistor output, Darlington output, PhotoMOS photorelay, triac output, IGBT and MOSFET gate driver, etc. — determines how the load is driven and how much drive current is needed;
- 封装形式与引脚定义——DIP-4、SOP-4、SOP-8、SO-8、DIP-8 等，需与现有 PCB 焊盘匹配。Package type and pin definition — DIP-4, SOP-4, SOP-8, SO-8, DIP-8, etc. — must match the pads of the existing PCB.
上述参数的取值请以对应型号的原厂规格书为准。For the values of the above parameters, please refer to the original manufacturer datasheet of the corresponding model.
你们有现货吗？起订量和交期怎么算？Do you have stock in hand? How are MOQ and lead time calculated?

AVAGO（安华高）和博通（Broadcom）是什么关系？What is the relationship between AVAGO and Broadcom?
安华高（Avago Technologies）与博通（Broadcom）是同一家公司。安华高最初是一家独立的光通信器件厂商，2005 年由安捷伦（Agilent）分拆上市，随后于 2016 年被博通收购，成为博通旗下的半导体业务。Avago Technologies and Broadcom are the same company. Avago was originally an independent optical communications component vendor, was spun off from Agilent and went public in 2005, and was acquired by Broadcom in 2016, becoming its semiconductor business.
因此行业里常说的 AVAGO、安华高、博通（Broadcom） 往往指的是同一条产品线——AVAGO / 安华高是历史品牌名，博通是收购方与现用的母公司名。Therefore, the terms AVAGO, Avago and Broadcom often used in the industry refer to the same product line — AVAGO / Avago is the historical brand name, while Broadcom is the acquirer and the current parent company.
博科信代理的 AVAGO 系列光耦（HCPL-181、HCPL-2231、HCPL-2232、HCPL-2601、HCPL-4503、HCPL-J312 等）即属于这条产品线，具体参数以对应型号页所附的原厂规格书为准。The AVAGO series optocouplers we distribute (HCPL-181, HCPL-2231, HCPL-2232, HCPL-2601, HCPL-4503, HCPL-J312, etc.) belong to this product line. For detailed parameters, please refer to the original manufacturer datasheet attached to the corresponding model page.
