ISL83071EIBZA-T 产品概述

一、产品简介

ISL83071EIBZA-T 是 RENESAS(瑞萨)推出的完全版差分收发器,集成 1 路驱动器与 1 路接收器,支持 RS422 与 RS485 两种差分通信标准。器件工作电压范围为 3.0V ~ 3.6V,专为工业级多点总线和可靠通信场景设计,兼顾低功耗与高可靠性,适合各种嵌入式与工业控制应用。

二、主要性能特点

  • 单通道收发结构:1 个驱动器、1 个接收器,支持点对点与多点拓扑。
  • 通信速率:最高 250 kbps,满足常见工业总线速率需求。
  • 节点支持:最多可挂接 256 个节点,适用于大规模 RS485 网络。
  • 通讯模式:支持全双工与半双工两种工作模式,可根据系统需求灵活配置。
  • 控制功能:提供 Tx / Rx 启用控制,引脚方便外部 MCU 实现总线管理与节能控制。

三、关键技术参数

  • 工作电压:3.0 V ~ 3.6 V(典型 3.3 V 系统兼容)。
  • 静态电流:510 μA(低功耗待机,有利于电池供电或能耗敏感系统)。
  • 数据速率:250 kbps。
  • 节点数:256(RS485 多点通信能力)。
  • 静电抗扰度:±15 kV(人体模型),提高现场抗静电能力。
  • 工作温度:-40 ℃ ~ +85 ℃(工业级温度范围)。
  • 封装:8 引脚 SOIC,便于 PCB 布局与标准 SMT 工艺。

四、功能与保护机制

  • Tx/Rx 启用:独立使能控制,实现总线仲裁、节能、远程唤醒等功能。
  • 热关断保护:器件具备过温检测与热关断机制,防止长时间过载导致元件损坏。
  • 过流保护:内置过流限制,保障短路或冲击电流时系统局部安全,降低失效风险。
    这些保护特性提升了设备在恶劣工业环境中的鲁棒性与长期可靠性。

五、典型应用场景

  • 工业自动化总线、PLC 与远程 IO 通信。
  • 楼宇自控、门禁与安防系统的多节点通信。
  • 数据采集与遥测终端(RTU)、仪表之间的差分通信。
  • 电机驱动监控、驱动器间通信以及需要抗干扰的串行链路。

六、封装与可靠性

ISL83071EIBZA-T 提供 8-SOIC 小型封装,适配标准插板与自动化贴装生产线。器件符合同类工业级电气与温度规范,±15 kV 的静电保护能力与 -40 ℃ 至 +85 ℃ 的工作温度范围,使其能够胜任野外与工业现场的苛刻工况。

七、设计建议与系统集成

  • 电源:建议采用滤波与去耦电容(靠近 VCC 引脚),以降低共模噪声对通信稳定性的影响。
  • 终端匹配:在总线两端使用合适的终端电阻以抑制反射,提升高速信号完整性。
  • 控制策略:在半双工模式下,通过 MCU 精确控制 Tx/Rx 使能,避免总线冲突。
  • 散热与保护:尽管集成热关断与过流保护,仍建议在设计中预留适当散热与保护电路,以延长寿命并提高可靠性。

总结:ISL83071EIBZA-T 是一款功能全面、适用于工业级 RS422/RS485 差分通信的收发器,具有低功耗、丰富的保护机制与良好的抗静电性能,是实现可靠多节点串行通信的理想选择。

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
