SN75176BDR(XBLW芯伯乐)差分收发器产品概述

一、产品定位与基本特性

SN75176BDR(XBLW芯伯乐)是一款半双工RS-485/RS-422差分收发器,兼容国际标准器件SN75176BDR,核心功能为实现单端信号与差分信号的双向转换,适用于短至中距离的多节点数据通信场景。其基本特性包括:

  • 单驱动器+单接收器配置,支持半双工通信;
  • 宽电压兼容(4.75V~5.25V),适配标准5V电源系统;
  • 最大支持32个总线节点,满足小型网络通信需求;
  • 商业级工作温度(0℃~+70℃),覆盖常规室内/一般工业环境;
  • 低静态电流(典型55mA),兼顾性能与电源效率。

二、关键参数详解

1. 电气参数

  • 工作电压:4.75V~5.25V(单电源供电,无需额外电压转换);
  • 静态电流:典型值55mA(发送/接收空闲时的电源消耗,低功耗设计减少发热);
  • 传输速率:支持最高2.5Mbps(满足大多数工业数据采集、设备通信的速率需求);
  • 差分输出摆幅:符合RS-485标准(-2V~+2V,确保信号抗干扰能力);
  • 总线负载:最大32个节点(每节点等效12kΩ负载,总线阻抗匹配后可稳定通信)。

2. 环境参数

  • 工作温度:0℃~+70℃(商业级,不适用于极端低温/高温环境);
  • 存储温度:-55℃~+125℃(常规器件存储要求)。

三、封装与引脚配置

SN75176BDR(XBLW)采用SOP-8贴片封装(8引脚窄体,尺寸紧凑),引脚功能与标准器件完全兼容,具体如下:

引脚编号 引脚名称 功能说明 1 DI 数据输入(单端TTL/CMOS电平) 2 /RE 接收使能(低电平有效,低=允许接收) 3 DE 发送使能(高电平有效,高=允许发送) 4 A 差分输出正/输入正(总线正端) 5 B 差分输出负/输入负(总线负端) 6 GND 电源地 7 RO 接收输出(单端TTL/CMOS电平) 8 VCC 电源正极(4.75V~5.25V)

四、典型应用场景

该器件适用于需要多节点、抗干扰通信的场景,核心应用包括:

  1. 工业自动化:PLC与传感器、执行器之间的RS-485总线通信(如温度采集、电机控制);
  2. 楼宇自动化:门禁系统、照明控制、消防报警的多节点总线网络;
  3. 小型数据采集:环境监测(温湿度、光照)的多传感器节点数据传输;
  4. 办公设备:打印机、复印机的内部串行通信扩展;
  5. 消费电子:智能家居设备(如智能插座、窗帘控制器)的组网通信。

五、应用注意事项

  1. 电源滤波:建议在VCC与GND之间并联0.1μF陶瓷电容,抑制电源噪声;
  2. 总线终端:长距离传输(>10m)需在总线两端并联120Ω终端电阻,匹配总线阻抗(避免信号反射);
  3. 使能控制:发送时需置DE=高、/RE=低,接收时置DE=低、/RE=高,避免总线冲突;
  4. 静电防护:SOP-8封装无内置ESD,建议在总线引脚(A/B)并联6V~8V TVS管,防止静电损坏;
  5. 温度限制:商业级器件,避免在低温(<0℃)或高温(>70℃)环境长期工作。

六、品牌与质量说明

XBLW(芯伯乐)是国内专注于模拟器件兼容替代的品牌,SN75176BDR(XBLW)严格遵循原器件电气规范,通过RoHS环保认证,可直接替换进口SN75176BDR,在保持性能一致的前提下降低BOM成本,适用于对成本敏感但要求稳定通信的场景。

该器件以其高兼容性、低功耗和紧凑封装,成为小型RS-485网络的常用选择,可满足多数常规通信场景的需求。

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
