ISL83485IBZ-T 产品概述

一、产品简介

ISL83485IBZ-T 是 RENESAS(瑞萨)推出的一款高可靠性半收发器,集成1路驱动器与1路接收器,兼容 RS-422/RS-485 差分通信标准。器件工作电压范围为 3.0V ~ 3.6V,工作温度范围为 -40℃ ~ +85℃,适用于工业级现场总线和嵌入式通信系统。封装为紧凑的 SOIC-8,型号标识为半-收发器-1-1-RS422-RS485-8-SOIC。

二、主要特性

  • 电源电压:3.0V ~ 3.6V,适合 3.3V 系统直接供电;
  • 通信速率:最高可达 10 Mbps,满足高速差分数据传输需求;
  • 网络拓扑:支持最多 32 个节点的多点网络,适用于常见 RS-485 总线结构;
  • 工作模式:半双工(half-duplex),单总线收发切换便捷;
  • 静态电流:静态工作电流约 650 µA,低功耗特性有利于能耗敏感型设备;
  • 工业级温度:-40℃ ~ +85℃,适合工业现场环境;
  • 封装:SOIC-8,便于 PCB 布局与自动化贴装。

三、典型应用

  • 工业自动化通信总线(如 PLC 与远程 I/O)
  • 楼宇控制与监控系统(HVAC、照明、门禁)
  • 过程控制与数据采集(传感器聚合、测量模块)
  • 电机驱动与运动控制通信链路
  • 其他需长距离差分通信或多节点网络的嵌入式系统

四、设计与使用要点

  • 差分信号布线:建议使用差分对,保持走线长度匹配并采用受控阻抗,以降低反射和串扰;
  • 终端与偏置:总线两端应采用合适终端电阻(一般与差分阻抗匹配)并在需要时提供偏置电路,保证空闲总线的确定电平;
  • 电源旁路:在 VCC 近旁放置 0.1 µF 陶瓷旁路电容以抑制高频噪声;
  • 过压/浪涌保护:工业现场建议在总线入口处加装共模电感与 TVS 垂直保护器件,以提高抗干扰与雷击浪涌能力;
  • 半双工控制:注意 DE/RE 控制逻辑的时序,在发送前后留足驱动使能/禁能时间以避免总线冲突;
  • 节点数与线缆长度:在高数据速率下可用距离会缩短,设计时需在速率与线长之间权衡,并考虑重发与误码检测机制。

五、封装与订购信息

  • 型号:ISL83485IBZ-T
  • 品牌:RENESAS(瑞萨)
  • 封装:SOIC-8(8 引脚)
  • 温度等级:工业级(-40℃ ~ +85℃)
  • 备注:器件为半双工 RS-422/RS-485 兼容收发器,适用于需要控制驱动/接收时序和网络保护的工业通信场景。

如需电气特性曲线、引脚定义和参考电路图,请参考 RENESAS 官方数据手册,以获得完整的时序、绝对最大额定值与典型应用建议。

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
