LM319DT 具有如下主要技术参数和特性:

  • 输出类型:支持开路集电极(Open-Collector)和开路发射极(Open-Emitter)输出形式,也兼容 TTL 输出,这使得其在连接到不同逻辑水平的电路时非常灵活。
  • 功耗:各通道的功耗为 12.5mA,适合低功耗设计应用。
  • 比较器组数:内置两个独立的比较器,便于处理多路信号的比较和监控。
  • 工作温度范围:适应的工作温度范围为 0°C 到 70°C,适合绝大多数工业和消费类电子产品应用。
  • 电源电压:电源电压范围为 5V 到 30V,支持单电源和双电源配置(±2.5V 到 ±15V),赋予设计灵活性。
  • 输入补偿电压(最大值):在 ±15V 电压下,输入补偿电压最大可达 8mV,保证了极其敏感的输入条件下可以保持准确的比较结果。
  • 输入偏置电流(最大值):±15V 供电下,输入偏置电流最大为 1µA,这一特性对降低功耗和提高线性度都至关重要。
  • 静态电流:静态电流最大为 12.5mA,适合于低功耗设计。
  • 封装形式:采用 14-SOIC 封装,尺寸为 0.154"(3.90mm 宽),适合表面贴装,可与自动化设备兼容,提升生产效率。

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
