XL485CS 产品概述

一、产品简介

XL485CS 是信路达(XINLUDA)推出的一款工业级 RS-485/RS-422 收发器,采用 SOP-8(150 mil)封装,内置一路驱动器与一路接收器(1 driver/1 receiver),工作电压范围为 4.5V ~ 5.5V,支持半双工通信,最高数据速率可达 10Mbps。器件面向多节点总线系统设计,支持最多 256 个节点的网络连接,并具有强抗静电能力(±15kV HBM),工作温度范围为 -40℃ 至 +85℃,静态(待机)电流约 600µA,适合工业、楼宇与仪表级通信应用。

二、主要特性

  • 支持 RS-485 与 RS-422 标准的差分收发功能,半双工通信模式(单对差分线)。
  • 单驱动×单接收配置,满足常见串行总线拓扑需求。
  • 工作电压:4.5V ~ 5.5V,兼容 5V 系统。
  • 最大数据速率:10 Mbps,适用于高速串行数据传输。
  • 总线节点支持:最多 256 节点(系统设计需考虑总线负载与终端阻抗)。
  • 静电保护:符合 ±15kV 人体模型(HBM)级别,提高现场抗扰能力。
  • 宽温工作:-40℃ ~ +85℃,适合恶劣环境。
  • 低功耗待机:静态电流约 600µA,有利于能耗敏感应用。
  • 封装:SOP-8(150 mil),便于 PCB 布局与量产组装。

三、典型引脚与连接建议

XL485CS 典型引脚包含:差分输出/输入对(A、B)、驱动输入(DI)、接收输出(RO)、驱动使能/方向控制(DE/RE 或 RE\̄ / DE),电源(VCC)与接地(GND)。

  • 总线连接建议:沿用 RS-485 标准,在线两端并联终端电阻(典型 120Ω),并在系统设计中视需要加入偏置/失效保护电阻以确保空闲总线确定电平。
  • 电源去耦:VCC 与 GND 之间建议放置 0.1µF 陶瓷去耦电容靠近器件电源引脚。
  • ESD/浪涌防护:若用于长期户外或强干扰场合,建议在线路处加入 TVS 二极管或共模扼流圈以增强瞬态抑制能力。

四、应用场景

适用于楼宇自动化(楼宇总线、门禁、照明控制)、工业控制与监控(PLC 通信、传感器网络)、仪表与数据采集系统、安防监控、能源管理以及其它需要差分半双工高速通信的场合。

五、使用与 PCB 布局建议

  • 差分对走线尽量成对且长度匹配,避免不必要的弯曲与跨越噪声源。
  • 终端与偏置电阻应放置在总线两端和靠近收发器的位置,以保证信号完整性与总线失效保护。
  • 电源与地平面应连续以降低环路阻抗,去耦电容靠近电源引脚布置。
  • 为提高可靠性,敏感信号线与高频、高电流走线保持隔离。

六、封装与可靠性

XL485CS 提供 SOP-8(150 mil)封装,便于通用插装与回流焊接。器件设计满足工业级温度与抗静电要求,适合长期工作于噪声与电磁干扰较高的现场环境。采购时请留意信路达官方型号与批次信息以确保质量一致性。

如需更详细的引脚排列、典型时序图或电气特性曲线(如差模电压范围、故障保护参数、短路容限等),建议向信路达索取正式数据手册以获得完整规范与参考设计。

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
