74HC04D 产品概述

一、简介

74HC04D 是基于先进 CMOS工艺设计的六路反相器(六个独立的 NOT 门),每路输出采用缓冲级的推挽结构,具备良好的驱动能力和抗干扰性能。逻辑功能与经典的 54/74 系列兼容,可在 2V~6V 单电源下稳定工作,适合低功耗数字电路的逻辑反相和缓冲应用。

二、主要性能指标

  • 工作电压(VCC):2.0V ~ 6.0V
  • 静态电流(Iq):典型 5.5 µA(全片静态功耗低)
  • 通道数 / 输入数:6 路独立反相器,6 个输入
  • 输出驱动:拉/灌电流 IOH / IOL ≈ 5.2 mA(典型)
  • 输入/输出电平(取决于 VCC 与负载):示例参数提供如下,实际以数据手册为准
    • VIH(高电平输入)示例:3.15V / 1.5V / 4.2V(对应不同测试条件)
    • VIL(低电平输入)示例:500 mV / 1.35V / 1.8V
    • VOH(高电平输出)示例:5.2V / 1.9V / 3.7V
    • VOL(低电平输出)示例:100 mV / 500 mV / 400 mV
  • 传播延迟(tpd):约 17 ns @ VCC = 5V,CL = 15 pF
  • 器件系列:74HC(高速 CMOS 兼容系列)
  • 工作温度:0 ℃ ~ +60 ℃
  • 品牌:GR(国睿)
  • 封装:DIP-14

三、功能特点

  • 低静态功耗:采用 CMOS 结构,静态电流小,适合电池供电或低功耗系统。
  • 缓冲推挽输出:较强的输出驱动能力,能直接驱动一般数字负载与小功率指示器件。
  • 高噪声抑制:输入阈值与噪声裕量合理,抗干扰能力好。
  • 兼容性强:逻辑功能与 54/74 系列兼容,便于与传统 TTL/CMOS 器件混合使用。
  • 响应速度:在合理负载下具备较低的传播延迟,适合中高速逻辑应用。

四、典型应用场景

  • 通用逻辑反相与缓冲:用于信号取反、整形与驱动。
  • 时序电路与组合逻辑模块:配合其它逻辑门实现复杂逻辑功能。
  • 小功率指示与驱动:驱动 LED(需限流)、继电器驱动前级放大等低电流场合。
  • 测试与原型开发:DIP 封装便于面包板实验与快速验证电路。

五、使用建议

  • 供电与旁路电容:建议在 VCC 与 GND 之间放置 0.01 µF~0.1 µF 陶瓷旁路电容,靠近器件电源引脚以抑制瞬态噪声。
  • 负载限制:单路典型驱动能力为 5.2 mA,避免长期驱动大电流负载或重电容性负载,以免扩大传播延迟或引起电平失真。
  • 输入状态定义:不使用的输入应接到确定电平(高或低),以防止浮空引起的功耗增加或振荡。
  • 温度与电压范围:保证工作温度与 VCC 在规定范围内,超出规范可能影响逻辑阈值与可靠性。
  • 布局注意:长导线或大电容负载会增加延迟并可能引入振铃,必要时在输出端加阻尼或缓冲级。

六、封装与采购信息

GR(国睿)品牌 74HC04D 常见为 DIP-14 封装,便于原型开发与小批量手工焊接。采购时请确认品牌、封装、件号及数据手册,确保参数(尤其是阈值、电流与时序)满足具体应用需求。

总结:74HC04D 以其低功耗、高兼容性和良好的驱动能力,是通用数字电路中常用的反相器件,适合教学、原型与中低速逻辑系统应用。

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.

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
