LM339G-P14-R 产品概述
一、产品简介
LM339G-P14-R 是 UTC（友顺）推出的一款四路比较器，型号封装为 TSSOP-14。该器件面向通用模拟比较和电平检测场景，描述信息为“未分类”。器件设计兼顾低功耗与高精度，便于嵌入式与工业控制系统中与微控制器或逻辑电平直接配合使用。
二、主要参数
- 比较器数：4 路
- 输出模式：DTL / TTL / CMOS 兼容
- 工作温度：-20℃ ～ +85℃
- 静态电流 (Iq)：1.1 mA（整芯片典型值）
- 输入失调电压 (Vos)：1.5 mV（典型/最大值视测试条件而定）
- 输入偏置电流 (Ib)：57 nA
- 封装：TSSOP-14
- 品牌：UTC（友顺）
三、核心特点
LM339G-P14-R 具备多路集成、低输入偏置电流与较小的输入失调电压，适合对精度有一定要求的门限检测。其输出与常见逻辑家族兼容，便于系统集成。器件通常采用开漏/开集电极输出结构（注意配合上拉电阻使用），从而实现灵活的电平拉升与多点线与功能。
四、典型应用场景
适用于电源监控与欠压/过压检测、ADC 前端比较、温度或传感器阈值判断、电平转换、开关去抖与工业控制信号判别等场景。四路并置设计有利于节省 PCB 面积并降低系统成本。
五、封装与可靠性建议
TSSOP-14 封装适合中高密度 SMT 工艺，焊接性与散热性能良好。实际设计时建议做好电源去耦、输入保护（如限流或 RC 滤波）与上拉电阻选型，以防止振荡或误触发。在极端温度或噪声环境中，应评估 Vos 与漂移对系统精度的影响。
六、选型与使用注意事项
选型时确认系统供电电压、输入共模范围与输出拉升电压相容性；若需驱动较大负载或长线通信，应适当降低上拉电阻并验证功耗与响应时间。布线上注意将敏感比较节点与噪声源分离，必要时增加滤波或滞后电路以提高抗干扰能力。
总结：LM339G-P14-R 以其四路集成、低偏置电流与与多种逻辑兼容的输出特性，为通用比较应用提供了可靠且经济的解决方案。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
