LM339M/TR 产品概述

一、产品简介

HGSEMI(华冠)LM339M/TR 是一款高稳定性的四路比较器,封装为 SOP-14,适用于工业和消费类模拟信号比较应用。器件输出兼容 TTL 与 CMOS 电平,具有低输入失调和低静态电流特点,支持宽电源电压范围,可单电源或对称双电源工作,适合电池供电或多电压系统中的比较与电平检测任务。

二、主要参数

  • 比较器通道数:4 路
  • 输入失调电压 (Vos):典型 2 mV
  • 输入偏置电流 (Ib):典型 25 nA
  • 输入失调电流 (Ios):典型 5 nA
  • 传播延迟 (tpd):典型 300 ns
  • 输出模式:开集电极输出,兼容 TTL / CMOS 电平(需上拉电阻)
  • 静态电流 (Iq):典型 800 μA
  • 工作温度范围:0℃ ~ +70℃(商业级)
  • 最大电源差值 (Vdd - Vss):36 V
  • 单电源工作范围:3 V ~ 32 V
  • 双电源工作范围:Vee ~ Vcc = 1.5 V ~ 16 V(对称)或 -16 V ~ -1.5 V
  • 封装:SOP-14(TR 表示卷带编带供应)

三、器件特性与优势

  • 精度:输入失调电压仅 2 mV,适合对精度有一定要求的阈值检测场合;低输入失调电流与偏置电流有利于高阻抗源直接驱动输入。
  • 低功耗:典型静态电流 800 μA,使得在电池供电或功耗受限的系统中具有优势。
  • 宽电源范围:支持 3 V 至 32 V 单电源或 ±1.5 V 至 ±16 V 的对称供电,便于在多种供电架构中使用。
  • 通用输出接口:开集电极输出可通过外接上拉电阻适配多种逻辑电平(TTL/CMOS),便于与微控制器、逻辑门、电平转换器对接。
  • 多通道集成:四路比较器在单芯片内集成,节省 PCB 面积并简化电路布局。

四、典型应用场景

  • 电压监测与电池电量检测:阈值检测、欠压/过压指示。
  • 零交叉检测与波形整形:交流信号检测与整流后比较。
  • 多路模拟开关与窗口比较:多通道同时比较不同输入电平。
  • 数据采集前端:模拟量与数字逻辑接口前的阈值判别与限幅。
  • 工业控制与传感器接口:限位检测、事件触发等低速比较任务。

五、设计与使用建议

  • 上拉电阻选择:由于输出为开集电极,需要外接上拉电阻以产生有效输出电平。上拉阻值影响上升时间与功耗,选择时在响应速度与电流消耗间权衡(典型从 4.7 kΩ 到 100 kΩ 不等,依据系统要求)。
  • 电源滤波与去耦:在每个器件电源近旁放置 0.1 μF 陶瓷去耦电容以抑制瞬态噪声,必要时增加 1 μF~10 μF 电解电容做全局滤波。
  • 输入保护:若输入可能出现超出供电轨的电压,建议增加限流电阻或保护二极管,防止输入结构受损或影响比较器性能。
  • 热与环境:工作温度为 0℃~+70℃,适合商业环境;如需扩展到工业温度范围,请选用对应等级的器件或进行额外评估。
  • 布局注意:将比较器敏感输入线短且远离开关噪声源,减小输入引线电容与干扰,确保稳定比较性能。

六、封装与订购信息

  • 封装形式:SOP-14,便于自动化贴装与中小批量生产。
  • 订购代码:LM339M/TR(TR 表示按卷带(tape & reel)包装,适合 SMT 生产线)。
  • 品牌:HGSEMI(华冠),提供商业级可靠性和常规质量支持。

综上所述,HGSEMI LM339M/TR 是一款通用性强、供电范围宽、低功耗的四路比较器,适合各类低速到中速的阈值检测与逻辑接口场景。在具体设计中,应注意上拉电阻、电源去耦与输入保护等细节,以发挥器件的最佳性能。若需更详细的电气特性曲线、引脚分配或典型应用电路,请参考 HGSEMI 的完整数据手册。

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.
