SN74LS04DR(LX) 反相器产品概述

一、产品基本信息

SN74LS04DR(LX)是灵星芯微(LX) 推出的6通道TTL逻辑反相器,属于经典74LS系列产品,采用SOP-14表面贴装封装。该器件专为数字电路中的信号逻辑反转需求设计,支持宽温范围(-40℃~+125℃)工作,可满足工业、车载等严苛场景的可靠性要求。

二、核心电气参数详解

该反相器的关键参数决定了其应用适配性,具体如下:

  1. 工作电压范围:2V~6V,覆盖低压(如3.3V系统)到中压(如5V传统TTL系统)的常见电源场景,兼容性强;
  2. 静态功耗:典型静态电流仅2μA,待机状态下功耗极低,适合电池供电或对功耗敏感的系统;
  3. 通道与功能:集成6个独立反相通道,可同时对多路数字信号进行“高→低”“低→高”逻辑反转,无需离散电路搭建;
  4. 输入输出电平特性:
    • 输入高电平(VIH):1.5V~4.2V,兼容TTL逻辑电平(VIH≥2V),支持部分低电压输入;
    • 输入低电平(VIL):500mV~1.8V,覆盖常见低电平范围(如TTL标准VIL≤0.8V);
    • 输出高电平(VOH):1.9V~5.9V,有效驱动后续逻辑电路;
    • 输出低电平(VOL):100mV~260mV,低电平噪声裕量充足;
  5. 驱动能力:灌电流(IOL)和拉电流(IOH)均为5.2mA,双向驱动均衡,可驱动中等负载(如LED、小型继电器辅助电路);
  6. 传播延迟:6V电源下典型值14ns,时序响应满足一般数字电路实时性要求。

三、封装与典型应用场景

SN74LS04DR(LX)采用SOP-14封装(尺寸约3.9mm×8.7mm),引脚间距1.27mm,体积紧凑,适合高密度PCB设计。典型应用包括:

  • 工业控制:PLC输入输出模块信号转换、传感器信号逻辑调理;
  • 车载电子:车载仪表、车身控制单元(BCM)的数字逻辑反转,宽温适配车载温度波动;
  • 消费电子:小型家电、智能设备的按键逻辑、LED显示驱动辅助电路;
  • 通信设备:数据链路信号极性调整、接口电路逻辑匹配。

四、性能优势与适用范围

该器件核心优势:

  1. 低功耗:2μA静态电流降低待机功耗,适合便携电池设备;
  2. 宽温宽压:-40℃+125℃工作温度+2V6V电源,覆盖工业/消费级需求;
  3. 高集成度:6通道集成减少离散元件,简化设计、节省PCB空间;
  4. 可靠驱动:5.2mA双向驱动确保负载兼容性,避免信号失真;
  5. 强兼容性:74LS逻辑电平与TTL/部分CMOS电路兼容,便于系统升级替换。

适用范围涵盖工业自动化、车载电子、消费数码、通信设备等领域,尤其适合多路逻辑反转+功耗/温度敏感场景。

五、使用注意事项

  1. 电源与输入限制:电源电压≤6V,输入电平≤当前电源电压(避免过压损坏);
  2. 负载驱动:输出负载电流≤5.2mA(灌/拉),避免过载发热失效;
  3. 焊接存储:SOP-14焊接需注意引脚间距防短路,存储用防静电袋;
  4. 环境要求:避免超温/高湿环境长期工作,确保可靠性。

该器件凭借低功耗、宽温宽压、高集成度等特性,成为数字电路逻辑反转的高性价比选择。

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
