ISL81487EIPZ 产品概述

一、产品简介

ISL81487EIPZ 是瑞萨(RENESAS)旗下的一款工业级串行收发器,提供 1 个驱动器与 1 个接收器,兼容 RS-422/RS-485 标准。器件工作电压范围为 4.5V 至 5.5V,支持最高 5 Mbps 的数据速率,工作温度范围为 -40℃ 至 +85℃,封装为常见的 8 引脚 PDIP,便于在工业控制与实验平台中直接插装使用。器件定位为半收发器(半双工/点到点或多点通信均可),适合对可靠性和现场可维护性要求较高的场合。

二、主要特点

  • 单通道收发(1 驱动 / 1 接收),满足常见串行链路需求
  • 支持 RS-422 与 RS-485 标准,兼容差分总线长距离传输
  • 宽电源电压:4.5V ~ 5.5V,方便与典型 5V 系统对接
  • 最高 5 Mbps 数据速率,适用于高速工业总线与测量应用
  • 工业级温度范围:-40℃ ~ +85℃,可靠性高
  • DIP-8 插装封装,便于原型验证、维修和替换

三、典型应用场景

  • 工业现场总线与PLC间通信接口
  • 测量仪器、数据采集模块的远程差分通信
  • 楼宇自动化、安防系统的多点总线拓扑
  • 运动控制与伺服驱动器的实时通信链路
  • 教学与实验平台、替换老旧 DIP 插件器件

四、电气与封装要点

  • 电源:VCC = 4.5V ~ 5.5V,建议上电滤波与旁路电容以保证瞬态稳定
  • 数据速率:最高 5 Mbps,实际链路速率受线缆长度、负载和拓扑影响
  • 工作温度:-40℃ ~ +85℃,适用于恶劣环境
  • 封装:PDIP-8,便于手工焊接与面包板调试
    注:具体引脚排列、使能/方向控制以及保护特性请参阅官方数据手册以确认接口细节。

五、设计与使用建议

  • 在差分对两端并联 120Ω 终端电阻以减少反射,必要时在主从节点建立偏置(pull-up/pull-down)以实现 fail-safe。
  • VCC 接近器件引脚处并联 0.1µF 陶瓷电容与 10µF 旁路电容,靠近电源引脚布板以抑制干扰。
  • 长线通信应考虑共模抑制、接地回路与浪涌保护,可外置 TVS 或共模电感提升抗扰度。
  • DIP 封装便于维修,但布局时留意散热与引脚间距,避免近旁大电流回路产生干扰。
  • 量产前务必参考瑞萨完整数据手册进行时序、引脚功能和可靠性验证。

六、采购与资料

建议通过瑞萨正规代理或授权分销商采购,并下载 ISL81487EIPZ 的官方数据手册获取完整电气规格、引脚图与典型应用电路。若需不同封装或更高集成度的器件,可在数据手册与供应链中查询兼容或替代型号。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
