SP485EEN-L/TR 产品概述

一、概述

SP485EEN-L/TR 是 ElecSuper(静芯微)推出的一款高可靠性差分半双工收发器,封装为 SOP-8,适用于工业总线和长距离数据传输场合。器件在宽工作温度范围下保持稳定性能,兼顾低功耗与高速通信能力,适合集成在多节点网络系统中。

二、主要特性

  • 工作温度:-40℃ 至 +125℃,满足严苛工业环境要求。
  • 工作电压:4.5V ~ 5.5V,兼容常见5V系统。
  • 数据速率:最高可达 14 Mbps,支持高速差分传输。
  • 静态电流:典型 300 μA,便于低功耗设计。
  • 通讯模式:半双工(Half-duplex),一个差分驱动器与一个差分接收器。
  • 驱动器/接收器:1 驱动器、1 接收器。
  • 支持节点数:多达 256 节点,适合大规模总线拓扑。
  • 静电保护:±15 kV(接触),增强现场抗干扰能力。
  • 封装:SOP-8,便于表面贴装与自动化生产。

三、功能亮点

  • 高共模抑制与差分输入结构,保障长线传输数据完整性。
  • 低静态电流设计,在待机或空闲总线状态下降低系统能耗。
  • 强化ESD与浪涌容限,提升产品在工业现场的可靠性与寿命。
  • 支持大节点数量,适用于楼宇自控、工业控制网络、远程采集等场景。

四、典型应用

  • RS-485/RS-422 工业现场总线、楼宇自动化(BAS)系统。
  • 数据采集与远程终端单元(RTU)、智能电表、环境监测节点。
  • 人机界面(HMI)与可编程逻辑控制器(PLC)之间的差分通信。
  • 多节点串行网络、长距离传感器网络与楼层通讯骨干。

五、设计注意事项

  • 推荐在差分对附近添加终端电阻(例如120 Ω)来匹配传输线阻抗,减少反射。
  • 在存在强电磁干扰的场合,建议使用共模扼流圈并做好接地与屏蔽。
  • 当网络节点数接近上限时,应评估总线负载与驱动能力,必要时采用中继或分段设计。
  • 供电需稳定在 4.5V~5.5V 范围内,电源旁路电容建议靠近 VCC 引脚布置。

六、封装与可靠性

SP485EEN-L/TR 提供 SOP-8 表面贴装封装,适配常规贴片工艺。器件在 -40℃ 至 +125℃ 的工作温度范围与 ±15 kV 的静电防护能力,满足工业级可靠性要求,可在恶劣环境中长期运行。

七、品牌与订购

品牌:ElecSuper(静芯微)。型号:SP485EEN-L/TR。适用于需要高节点数、低功耗与工业级耐受能力的差分总线应用。订购时请确认规格书与存储条件,亦可联系供应商获取样片和技术支持。

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
