74HC08DMT/TR 产品概述

74HC08DMT/TR是华冠半导体(HGSEMI)推出的74HC系列4通道2输入与门,采用CMOS工艺制造,兼具低功耗、高速逻辑运算能力与宽电压适配性,是数字电路中实现“逻辑与”功能的常用器件,广泛应用于工业控制、消费电子等领域。

一、产品基本信息

该器件包含4组独立的2输入与门,每通道实现逻辑与运算(仅当两个输入均为高电平时输出高电平,任一输入为低电平则输出低电平)。属于74HC系列标准逻辑器件,引脚功能与行业通用74HC08完全兼容,可直接替换同系列竞品,降低设计与采购成本。

二、核心性能参数

1. 逻辑与通道配置

  • 逻辑类型:与门
  • 通道数:4通道(每通道2输入)
  • 输入/输出逻辑:CMOS电平兼容

2. 电压与电流特性

  • 工作电压范围:2V~6V(覆盖3.3V、5V等常见逻辑电平系统)
  • 静态电流(Iq):5.5μA(典型值)(低功耗特性,适合电池供电或低功耗场景)
  • 动态电流:随工作频率变化,静态下功耗极低

3. 电平特性(典型值,不同Vcc下)

电源电压(Vcc) 输入高电平(VIH) 输入低电平(VIL) 输出高电平(VOH) 输出低电平(VOL) 2V ≥1.5V ≤0.5V ≥1.9V - 4.5V ≥3.15V ≤1.35V 3.7V~4.4V ≤0.4V 6V ≥4.2V ≤1.8V 5.2V~5.8V ≤0.1V

4. 高速性能

  • 传播延迟(tpd):18ns(典型值,Vcc=5V、负载电容15pF)
  • 切换速度:上升/下降时间快,适配高速数字系统需求

三、封装与引脚说明

  • 封装类型:TSSOP-14(薄型小外形封装,14引脚),尺寸紧凑(约4.4mm×3.0mm),适合高密度PCB设计
  • 引脚排列(顶视图,从左到右):
    1. 1A(通道1输入A)→ 2. 1B(通道1输入B)→ 3. 1Y(通道1输出)
    2. 2A(通道2输入A)→ 5. 2B(通道2输入B)→ 6. 2Y(通道2输出)
    3. GND(地)→ 8. 3Y(通道3输出)→ 9. 3B(通道3输入B)
    4. 3A(通道3输入A)→ 11. 4Y(通道4输出)→ 12. 4B(通道4输入B)
    5. 4A(通道4输入A)→ 14. Vcc(电源)

四、应用场景

该器件因性能均衡、兼容性强,广泛应用于以下场景:

  1. 地址译码:数字系统中地址线与控制信号的与运算,实现特定地址空间选通;
  2. 控制信号生成:如使能控制(需多个条件同时满足)、状态判断(逻辑与逻辑);
  3. 数据选通:多通道数据输入的选通控制,仅当选通信号为高时输出有效数据;
  4. 工业控制:适配-40℃~+85℃工作温度,满足工业现场设备逻辑控制需求;
  5. 消费电子:智能家居、便携式设备的低功耗逻辑电路设计。

五、工作环境与可靠性

  • 工作温度范围:-40℃~+85℃(工业级温度范围,适应严苛环境);
  • 抗干扰能力:CMOS工艺具备高抗噪性,输入阈值电压稳定;
  • 可靠性:符合RoHS标准,无铅封装,长期使用稳定性高;
  • ESD防护:具备行业标准ESD防护能力,降低生产/使用中的静电损伤风险。

六、品牌与优势

HGSEMI(华冠半导体)是国内专注于逻辑器件、电源管理的知名厂商,74HC08DMT/TR具备以下优势:

  1. 兼容性强:引脚与功能兼容行业通用74HC08,无缝替换;
  2. 性价比高:国产厂商供货稳定,成本低于进口竞品;
  3. 质量可靠:通过严格可靠性测试,满足工业级应用要求;
  4. 技术支持:提供完善datasheet与应用技术支持,降低设计难度。

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
