SN74LS04N(LX) 六反相器产品概述

一、产品基本信息

SN74LS04N(LX)是灵星芯微(LX)推出的74LS系列六反相器,属于TTL逻辑器件范畴,核心功能为6路独立逻辑反相——即对每一路输入信号实现“高电平转低电平、低电平转高电平”的运算。该器件采用DIP-14双列直插式封装,引脚布局与标准74LS04完全兼容,可直接替换传统同类产品,适用于数字电路逻辑电平转换、信号缓冲等场景。

二、核心电气参数

该器件的关键参数覆盖了功耗、电压、驱动能力等核心维度,具体如下:

  • 工作电压:2V~6V(突破传统74LS以5V为主的限制,适配3.3V、5V等主流电源);
  • 静态电流(Iq):仅2μA(远低于普通TTL器件,大幅降低系统待机功耗);
  • 通道数:6路独立反相器,可同时处理多路信号;
  • 驱动能力:灌电流(IOL)与拉电流(IOH)均达5.2mA,驱动能力均衡,可直接驱动LED、小型继电器等负载;
  • 输入电平:高电平(VIH)1.5V4.2V,低电平(VIL)500mV1.8V,兼容多种输入信号;
  • 输出电平:低电平(VOL)稳定在100mV~260mV,噪声裕量充足,减少误触发;
  • 传播延迟(tpd):6V下仅14ns,响应速度快,满足中高速逻辑电路时序需求。

三、封装与引脚配置

采用DIP-14双列直插式封装,引脚编号与功能清晰(按1~14脚顺序):

  1. 1A/2A/3A/9A/11A/13A:6路反相器的输入引脚;
  2. 2Y/4Y/5Y/8Y/10Y/12Y:对应6路反相器的输出引脚;
  3. 7脚:接地(GND);
  4. 14脚:电源(VCC)。

DIP封装的优势在于插装方便,无需专用焊接工具即可完成原型开发,且耐机械应力性能较好,适合工业环境长期使用。

四、性能优势

  1. 低功耗:静态电流仅2μA,相比传统74LS器件功耗降低约90%,适合便携设备或电池供电系统;
  2. 宽电压适配:2V~6V范围可兼容3.3V单片机、5V传统数字电路,无需额外电平转换;
  3. 均衡驱动:灌/拉电流均为5.2mA,输出端驱动能力一致,避免负载响应不均;
  4. 高速响应:14ns传播延迟可满足100MHz以下中高速电路需求(如信号处理、通信接口);
  5. 工业级可靠性:工作温度覆盖-40℃~+125℃,符合工业级标准,可在极端环境下稳定工作。

五、典型应用场景

  1. 逻辑电平转换:适配3.3V单片机与5V外设(如传感器、继电器)之间的电平匹配;
  2. 多路信号反相:工业控制中多路传感器信号的反相处理,或数字电路逻辑电平调整;
  3. 信号缓冲驱动:增强弱信号驱动能力,直接驱动LED指示灯、小型继电器线圈;
  4. 原型开发:DIP封装易插拔,适合高校实验、电子爱好者的原型制作;
  5. 工业控制模块:PLC输入输出接口、电机控制电路中的逻辑电平转换环节。

六、兼容性与替换

该器件完全兼容标准74LS04的引脚布局与逻辑功能,可直接替换TI(SN74LS04N)、NXP(74LS04)等同类产品,无需修改电路设计,降低系统升级成本。同时,其TTL逻辑电平与74LS、74HC等系列器件兼容性较好,可协同工作。

SN74LS04N(LX)凭借低功耗、宽电压、工业级可靠性等优势,成为数字电路中逻辑反相、电平转换的实用选择,适用于消费电子、工业控制、原型开发等多领域。

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
