ISL3173EIUZ-T 产品概述

一、产品简介

ISL3173EIUZ-T(RENESAS)是一款全双工差分收发器,封装为 MSOP-10,型号描述为“完全版-收发器-1-1-RS422-RS485-10-MSOP”。器件集成1路驱动器和1路接收器,工作于3.0V~3.6V电源电压,面向紧凑型、低功耗且抗干扰能力要求高的RS-422/RS-485现场总线应用。

二、主要性能特点

  • 通讯模式:全双工,独立驱动与接收通道,适合点对点或多节点拓扑的同时收发需求。
  • 数据速率:支持最高500 kbps,满足常见工业控制与数据采集速率要求。
  • 节点能力:总线最大可连接256个节点,适合大规模分布式系统。
  • 工作电压:3.0 V–3.6 V(典型3.3 V),可直接与3.3 V逻辑电平兼容,方便单片机/FPGA接口。
  • 静态电流:静态电流仅约510 μA,有利于低功耗系统设计和电池供电场景。
  • 温度范围:工业级工作温度 -40 ℃ 至 +85 ℃,适应严苛环境。
  • 静电保护:对人体模型/系统接口级别有±15 kV 抗静电能力,提高现场可靠性。
  • 封装:MSOP-10,小尺寸占板面积小,适合空间受限的应用。

三、应用场景

  • 工业自动化与现场总线(PLC、I/O模块)
  • 楼宇自控与安防系统(门禁、HVAC 控制)
  • 仪器仪表与数据采集(远程测量节点)
  • 交通与电力通信接口(计量、监控)
  • 任何需要3.3 V差分串行通信且要求高ESD、工业温度的嵌入式系统

四、典型设计与布局建议

  • 终端匹配:总线上两端建议采用120 Ω 差分终端电阻以减少反射。
  • 偏置与失效保护:在多节点网络中应设置适当的总线偏置电阻(bias)以保证空闲总线的已知电平;具体阻值与器件失效/空闲策略请参照器件详细手册。
  • 差分对布线:保持差分对等长、等宽,尽量采用受控阻抗走线并减少急转弯,缩短共模敏感环路面积。
  • 电源完整性:靠近器件放置0.1 μF或更大值的旁路电容,铺地或散热铜箔以改善热性能与EMC。
  • ESD与浪涌保护:尽管器件提供 ±15 kV 静电保护,必要时在接口处并联TVS或共模滤波器以增强对浪涌的防护。

五、选型与可靠性提示

  • 在需要更高数据速率或更强驱动能力的场合,请对比器件的驱动电流和传输距离参数;本器件在500 kbps 内表现优异。
  • 工业温度范围和高ESD等级适合现场布线环境,但实际系统还需考虑接地、屏蔽和接线质量以保证长期可靠性。
  • 参考原厂数据手册获取详细电气参数、引脚定义与时序,特别是欠压锁定、失效模式和总线仲裁相关信息。

六、总结

ISL3173EIUZ-T 是一款面向工业现场与嵌入式应用的紧凑型、低功耗、抗静电全双工RS-422/RS-485收发器。凭借3.0–3.6 V 工作电压、500 kbps 数据速率、256 节点支持与±15 kV 静电保护,适用于对空间、电源和环境可靠性有较高要求的串行差分通信场合。选型时建议结合系统拓扑与传输距离进行总线终端与偏置设计,并遵循差分布线与电源旁路的最佳实践。若需产品手册、引脚图或评价板资料,请咨询RENESAS官方文档。

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
