CD4081BE 四路两输入与门(HGSEMI 华冠版)产品概述

一、产品简介

CD4081BE 是标准 4000 系列 CMOS 器件中的四路两输入与门(quad 2-input AND)。本器件在宽电源电压范围内工作(5V–15V),静态电流低,输出摆幅接近电源轨,适合低功耗逻辑与信号组合场合。HGSEMI(华冠)生产的 CD4081BE 采用 DIP-14 封装,便于面包板和通孔电路板使用。

二、关键技术参数

  • 逻辑类型:与门(AND),每路 2 输入,共 4 路
  • 工作电压:5V ~ 15V
  • 静态电流 Iq:典型 1 μA(无负载时)
  • 输入电平(典型阈值,随 VDD 变化):
    • VDD = 5V:VIH ≈ 3.5V,VIL ≈ 1.5V
    • VDD = 10V:VIH ≈ 7V,VIL ≈ 3V
    • VDD = 15V:VIH ≈ 11V,VIL ≈ 4V
  • 输出电平(开集电近似):
    • VDD = 5V:VOH ≈ 4.95V
    • VDD = 10V:VOH ≈ 9.95V
    • VDD = 15V:VOH ≈ 14.95V
  • 输出低电平:VOL ≈ 50 mV(典型,取决于负载)
  • 传播延迟 tpd:约 20 ns(VDD = 15V,CL = 50 pF)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:DIP-14

注:上列阈值为典型值,实际门限与工艺、温度和负载有关,设计时应参考完整规格书中的最小/最大限值。

三、引脚与封装(常见映射)

DIP-14 引脚排列(建议在设计前以实际数据手册为准):

  • Pin1:1A,Pin2:1B,Pin3:1Y
  • Pin4:2A,Pin5:2B,Pin6:2Y
  • Pin7:VSS(GND)
  • Pin8:3Y,Pin9:3B,Pin10:3A
  • Pin11:4Y,Pin12:4B,Pin13:4A
  • Pin14:VDD(电源)

四、典型电气特性说明

  • 输入阈值随 VDD 近似成比例变化(VIH ≈ 0.7·VDD,VIL ≈ 0.3·VDD);因此在不同电源下推断可靠逻辑电平时需按相应 VDD 数值计算。
  • 输出能够将 VOH 拉近 VDD,VOL 很低,适合驱动高阻负载或进一步 CMOS 级联。
  • 传播延迟与 VDD 和负载电容显著相关:电压越高、负载越轻,开关越快;在 5V 条件下延迟会比 15V 情况明显增加。
  • 静态电流小,但当输入悬空或处于模拟阈值区时电流可能增加,建议输入不悬空。

五、典型应用场景

  • 组合逻辑单元:地址解码、使能逻辑、条件判断等。
  • 信号门控:在电源允许范围内作为开关或与非门组合实现复杂逻辑。
  • 低功耗设计:便于电池供电的数字子系统(注意速度与电压权衡)。
  • 教学与原型:DIP 封装适合面包板实验与教学演示。

六、工程建议与注意事项

  • 电源旁路:在 VDD 与 VSS 之间并联 0.01–0.1 μF 陶瓷电容,减小瞬态和噪声。
  • 输入勿悬空:所有输入应接明确电平或通过上拉/下拉电阻稳定,避免静态电流异常或不确定输出。
  • 负载与驱动能力:驱动大电容或多级 TTL/CMOS 时需评估扇出或并联缓冲器。
  • 温度与容差:工作环境极端时参考完整数据手册的温度特性与最大/最小参数。
  • ESD 与稳态保护:遵循常规静电防护与电源升降速率管理,避免器件误触发或损坏。

七、与其他逻辑电平兼容性

在 5V 工作时,输入阈值(VIH ≈ 3.5V)对传统 TTL 兼容性需注意:TTL 输出高电平若不足 3.5V,可能无法被完全识别为高电平,必要时加上电平转换或上拉。总体而言,CD4081BE 适合与其他 CMOS 器件级联,但与老旧 TTL 器件接口时需验证电平裕度。

结语:CD4081BE(HGSEMI)为通用、低功耗的四路 2 输入与门器件,适用范围广,使用时请以厂家完整数据手册为准并注意输入/输出电平与电源条件的匹配。若需更精确的最小/最大参数或波形实例,我可帮助检索并解析对应数据手册条目。

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.
