  • 支持多节点拓扑(高达 256 节点),利于组网与远程设备接入。
  • 封装:SOP-8,便于通用 PCB 设计与量产贴片。

三、典型应用场景

  • 工业控制网络及现场总线接口模块
  • 楼宇自动化与安防系统的数据通信节点
  • 智能表计、远程抄表与能源管理终端
  • 串口转差分总线模块(如 RS-485/RS-422 等差分应用)
  • 嵌入式网关、PLC 通信接口与分布式控制单元

四、电气规格(概览)

  • 工作电压:VCC = 3.3V(典型)
  • 静态电流:约 1.5 mA(待机/待命状态典型值)
  • 最大数据速率:500 kbps
  • 工作温度范围:-40℃ ~ +85℃
  • ESD 抗扰:±15 kV(人体模型)
  • 驱动器/接收器:1/1(全双工)
  • 支持节点数:最多 256 节点
  • 封装类型:SOP-8

(注:详细的电气极限值、时序图与特性曲线请参阅厂商规格书以获得准确数值与测试条件。)

五、接口与功能说明(要点)

  • 驱动器输入(DI):TTL/CMOS 电平输入,用于发送数据。
  • 驱动器差分输出(A/B 或 Y/Z):连接差分总线,提供驱动能力与线路保护。
  • 接收器差分输入(A/B 或 Y/Z):从差分总线接收信号并转换为单端输出。
  • 接收器输出(RO):向主控器件输出接收数据。
  • 使能/方向控制(DE/RE 或类似管脚):控制驱动器使能与接收器状态,实现总线仲裁与方向管理。
  • 电源与地(VCC、GND):建议在 VCC 与 GND 之间靠近器件放置旁路电容(如 0.1 μF)。

六、布板与使用建议

  • 在 VCC 与 GND 之间放置高频旁路电容(0.1 μF)与陶瓷电容,靠近器件电源引脚以降低高频噪声。
  • 差分总线上的终端电阻(常用 120 Ω)应在总线两端并接,减少反射。
  • 若有强干扰或浪涌环境,建议在 A/B 差分线上增加外部 TVS 或共模电感进行保护与抑制。
  • 保持差分线对走线长度与阻抗匹配,减少串扰与时延不匹配。
  • 在多节点拓扑中注意总线负载和节点位置,合理布置终端与偏置网络,以确保接收侧稳定性。

七、封装与订购信息

  • 封装形式:SOP-8(贴片)
  • 尺寸与引脚排列请以官方封装图为准,批量采购请通过正规代理或厂商授权渠道获得原厂料号 SP3074EEN-L/TR 以确保品质与售后支持。

八、注意事项

  • 在设计前务必参照 MAXLINEAR 官方数据手册获取完整电气规格、热特性与时序要求。
  • 若在高压共模或强干扰场景使用,应选配适当的外部防护器件并评估总线隔离方案。
  • 对于多节点(接近 256 节点)应用,需评估总线负载、线长与终端策略以保证信号质量与稳定通信。

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
