CD4077BM/TR 4通道异或非门产品概述

HGSEMI(华冠)推出的CD4077BM/TR是一款基于4000系列CMOS工艺的4通道异或非门(XNOR)器件,采用SOP-14表面贴装封装,具备宽电压范围、低功耗、高速响应等特性,适用于工业控制、消费电子、通信等领域的数字逻辑电路设计。

一、核心功能与逻辑特性

CD4077BM/TR内置4组独立的2输入异或非逻辑单元,属于典型的同或门器件:当两个输入信号完全相同(均为高电平或均为低电平)时,输出为高电平;当输入信号不同时,输出为低电平。该逻辑特性可直接用于数字信号的同态判断、奇偶校验等场景,无需额外逻辑转换。

作为4000系列CMOS器件,其核心优势在于宽电压兼容与低静态功耗,同时具备CMOS电路固有的高输入阻抗特性,对前级驱动电路的负载要求极低。

二、电气参数与性能优势

CD4077BM/TR的关键电气参数覆盖了宽范围应用需求,核心性能如下:

  1. 宽工作电压范围:支持3V~15V电源电压,可兼容5V、10V、15V等主流数字系统,无需额外电平转换电路即可适配不同电压域的设计。
  2. 充足驱动能力:灌电流(IOL)与拉电流(IOH)均为6.8mA,可直接驱动中小功率负载(如LED、小型继电器线圈等),减少外部驱动电路的设计复杂度。
  3. 精准输入输出电平:
    • 输入高电平(VIH):对应15V、10V、5V电源电压时,分别为11V、7V、3.5V;
    • 输入低电平(VIL):对应上述电源电压时,分别为1.5V、3V、4V;
    • 输出高电平(VOH):接近电源电压(如5V电源时为4.95V5V,15V电源时为14.95V15V);
    • 输出低电平(VOL):低至50mV,输出噪声极低,信号完整性优异。
  4. 高速响应:15V电源、50pF负载条件下,传播延迟(tpd)仅为50ns,满足多数高速数字逻辑场景的时序要求。

三、封装与工作环境

  1. 封装形式:采用SOP-14表面贴装封装,体积小巧(标准SOP14尺寸),适配自动化贴装生产线,同时支持手工焊接(需注意防静电)。
  2. 工作温度范围:-40℃~+85℃,符合工业级温度要求,可稳定工作于严寒、高温等恶劣环境,无需额外散热设计(功耗极低)。
  3. 品牌可靠性:HGSEMI(华冠)作为国内成熟的半导体厂商,其产品经过严格可靠性测试,可满足工业级、消费级等不同市场的质量要求。

四、典型应用场景

CD4077BM/TR的4通道同或逻辑特性使其在多个领域有广泛应用:

  1. 数字比较器:4组同或门可直接构成4位二进制数的同态比较器,判断两个4位数据是否完全一致;
  2. 奇偶校验电路:通过级联异或非门可实现8位/16位数据的奇偶校验(同或逻辑与异或逻辑互补,可灵活转换);
  3. 逻辑电平转换:宽电压范围使其可作为不同电压域(如3V与5V系统)之间的逻辑电平转换接口;
  4. 工业控制逻辑:用于PLC(可编程逻辑控制器)中的简单逻辑判断(如传感器信号的一致性检测);
  5. 消费电子信号处理:如遥控器编码校验、音频/视频信号的同步判断等。

五、选型与使用注意事项

  1. 兼容性:与其他4000系列CMOS器件(如CD4001或非门、CD4011与非门)引脚定义兼容,可直接替换同功能器件;
  2. 引脚定义:SOP-14封装引脚(典型):1/2(通道1输入)、3(通道1输出);4/5(通道2输入)、6(通道2输出);8/9(通道3输入)、10(通道3输出);11/12(通道4输入)、13(通道4输出);7(GND)、14(Vcc);
  3. 使用注意:CMOS器件需注意防静电(建议使用防静电工作台/手环);输入电平不得超过电源电压(Vcc)与地(GND)范围;驱动负载时需确保总电流不超过灌/拉电流上限(6.8mA/通道)。

总结:CD4077BM/TR作为一款高性价比的4通道异或非门,具备宽电压、高驱动、宽温工作等优势,是数字逻辑电路设计中同或功能实现的理想选择,可满足工业、消费电子等多领域的应用需求。

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
