MAX232EIM/TR 产品概述

一、产品简介

MAX232EIM/TR 是一款面向串行通信的双驱动器/双接收器电平收发器,适用于单电源环境下的TTL/CMOS与RS-232电平转换。器件内置电荷泵,可由单一5V供电生成通信所需的正负电压,便于在微控制器和传统串口设备间实现可靠的数据传输。

二、主要规格

  • 类型:收发器(电平转换器)
  • 驱动器数:2;接收器数:2
  • 支持数据速率:最高约140 kbps
  • 工作电压:4.5 V ~ 5.5 V(单电源)
  • 电荷泵:内置(需外接电容)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 静态电流:约14 mA
  • 封装:SOP-16
  • 品牌:HGSEMI(华冠)

三、功能特点与优势

  • 单电源供电,内置电荷泵免除外部双电源需求,节省系统设计复杂度。
  • 两路驱动、两路接收满足常见的全双工或多端口串行接口需求。
  • 低静态电流(约14 mA),适合对功耗有一定要求的嵌入式系统。
  • 宽温度范围和标准SOP-16封装,便于工业环境和现有PCB布局兼容。
  • 支持约140 kbps 的数据速率,覆盖大多数标准串口通信场景。

四、典型应用场景

  • 工业自动化中的串口通信模块(PLC、传感器网关)
  • 嵌入式系统与PC/终端的RS-232接口转换
  • POS、仪表、调制解调器和GPS模块等需要TTL/RS-232电平转换的设备
  • 需要单电源解决方案的空间受限或低成本产品

五、使用与设计注意事项

  • 电荷泵通常需外接四个旁路电容以生成正负电压,建议按照器件手册选择合适容值并靠近引脚布局放置。
  • 工作电压需严格控制在4.5 V~5.5 V范围,过压或欠压会影响电荷泵输出和通信稳定性。
  • 关注PCB走线和接地设计,减少共模干扰与串扰以提升高速通信可靠性。
  • 在工业环境下应考虑额外的ESD和浪涌保护措施。

六、封装与参考

MAX232EIM/TR 提供标准 SOP-16 封装,便于直接替代市场上常见的MAX232系列器件。参考设计应包括电荷泵电容布局、RS-232信号端的浪涌/ESD保护,以及与微控制器串口的互联示意,以加快产品开发与验证。

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
