MAX232CSE+T 产品概述

一、产品简介

MAX232CSE+T 是 ADI(原 Maxim/LINEAR)推出的一款双通道 RS-232 收发器,采用 16 引脚窄体 SOIC 封装(SO-Narrow-16),并以 +T 表示卷带(tape-and-reel)供货形式。器件内部集成电荷泵,可在单一 5V 电源下产生满足 RS-232 电平要求的正负电压,便于微控制器与传统串口设备直接互联。

二、主要参数

  • 类型:收发器(Transmitter/Receiver)
  • 驱动器数:2(双发射)
  • 接收器数:2(双接收)
  • 数据速率:116 Kbps(典型支持串行速率)
  • 工作电压:4.5 V ~ 5.5 V(单一电源)
  • 电荷泵:内置(无需外部双电源)
  • 工作温度:0 ℃ ~ +70 ℃(商业温度等级)
  • 静态电流:4 mA(静态电源电流)
  • 封装:SO-Narrow-16(16 引脚窄体 SOIC)
  • 品牌:ADI / LINEAR

三、功能特点

  • 内置电荷泵,外接少量电容即可生成 RS-232 所需正负电压,简化系统电源设计;
  • 两路 TTL/CMOS 侧输入/输出对应两路 RS-232 侧驱动/接收,适合典型串口应用;
  • 低静态电流(约 4 mA),适合对功耗有一定要求的系统;
  • 在 4.5 V 至 5.5 V 电源下稳定工作,适配常见 5V 嵌入式平台;
  • 商业温度等级(0~70 ℃),适用于一般工控、消费类或办公设备环境。

四、封装与引脚说明

MAX232CSE+T 提供 16 引脚窄体 SOIC(SO-Narrow-16)封装,占板面积小,便于表面贴装。+T 后缀表示卷带包装,适合自动贴片生产线。典型设计中需要为电荷泵外接四个电容(常用规格见数据手册),以保证电荷泵输出稳定并满足 RS-232 电平要求。

五、典型应用场景

  • 传统 RS-232 串口与微控制器或 FPGA 的电平接口转换;
  • 工业设备通讯、仪器仪表、POS 终端与打印机接口;
  • 嵌入式系统调试串口、数据采集模块的串行链路;
  • 需要低功耗、标准 RS-232 电平但仅有单 5V 电源的系统。

六、设计与使用建议

  • 外部电容:器件需配合电荷泵电容使用,建议按照官方数据手册推荐的数量与容值选型(常见为 1 µF 等),以确保输出电压和驱动能力;
  • 去耦与布线:VCC 处应做良好旁路去耦,GND 平面完整以降低噪声对串口信号的影响;
  • ESD 与浪涌保护:在工业环境或长线通信场景,建议在外部增加浪涌抑制或瞬态抑制器件以保护器件,提高可靠性;
  • 速率与线缆长度:虽器件支持约 116 kbps 的数据速率,实际可达速率与通信线缆特性、连接器质量和接地情况密切相关,设计时应做实际验证。

MAX232CSE+T 以其成熟的电荷泵架构、双通道设计和紧凑封装,为需要将 TTL/CMOS 逻辑与 RS-232 设备可靠连接的系统提供了简单、低成本的解决方案。欲获取详细引脚定义、电气限值和典型应用电路,请参考 ADI 官方数据手册。

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
