ISL81487LIBZ-T 产品概述
一、简介
ISL81487LIBZ‑T 是瑞萨（RENESAS）推出的一款单路 RS-485/RS-422 收发器，采用 BiCMOS 工艺、5V 供电，集成 ESD 保护并实现分数单位负载（fractional unit load），在工业通信和数据链路中提供可靠的差分收发能力。器件在 SOIC‑8 封装中提供，工作电压范围 4.5V ~ 5.5V，最高数据速率可达 5 Mbps，工作温度范围为 −40 ℃ 至 +85 ℃。
二、主要特性
- 类型：单收发器（1 驱动器，1 接收器）
- 通讯标准：兼容 RS‑485 与 RS‑422
- 供电电压：4.5V ~ 5.5V（典型 5V 系统）
- 数据速率：最高 5 Mbps，适合高速差分串行链路
- 负载特性：分数单位负载，允许在总线中连接更多节点
- 工艺与保护：BiCMOS 工艺、片上 ESD 保护，增强系统鲁棒性
- 工作环境：工业级温度范围 −40 ℃ 至 +85 ℃
- 封装：SOIC‑8，便于 PCB 布局与自动贴装
三、典型应用
- 工业自动化与现场总线（PLC、I/O 扩展）
- 楼宇控制与监控系统
- 数据采集与遥测设备
- 运动控制与伺服系统的通信链路
- 点对点和多点差分通信网络
四、设计与使用建议
- 电源旁路：在 VCC 引脚附近放置 0.1 µF 陶瓷旁路电容以抑制瞬态噪声。
- 终端匹配：长线或高速链路建议在差分线上使用 120 Ω 终端电阻以减少反射；多点网络按需配置偏置电阻以保证空闲总线的确定电平。
- 布线建议：差分对应尽量成对、等长并靠近地平面布线，减少串扰与 EMI。
- ESD 考虑：尽管芯片具备 ESD 保护，外部连接器处仍建议增加保护器件以应对强干扰环境。
- 工作电压与温度：确保系统电源稳定在 4.5V~5.5V，并在极端温度下验证通信性能。
五、封装与订购
ISL81487LIBZ‑T 提供 SOIC‑8 封装，适用于面向工业应用的自动化生产线。订购时请参考瑞萨官方数据手册以获取包装方式、温度等级和基带测试信息。

Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
