CD4528BM/TR 单稳态触发器产品概述

一、产品核心身份与系列归属

CD4528BM/TR是华冠半导体(HGSEMI)推出的双通道单稳态触发器,属于经典CMOS逻辑40XX系列成员。该器件采用16引脚小外形封装(SOP-16),专为数字电路中的脉冲定时、信号整形及抗干扰场景设计,具备宽电压兼容、超低功耗等核心特性,是工业控制、便携设备等领域的实用型逻辑器件。

二、关键电气参数与性能亮点

CD4528BM/TR的电气参数针对实际应用场景做了优化,核心性能可满足多数数字系统需求:

  1. 宽电压工作范围:支持3V~15V直流电源输入,兼容3.3V、5V、12V等主流系统电源,无需额外电平转换电路,降低设计复杂度;
  2. 超低静态功耗:典型静态电流仅5nA,远低于普通逻辑器件的微安级功耗,适合电池供电的便携设备(如手持测试仪、智能传感器)或长期待机的低功耗系统;
  3. 稳定时序响应:传播延迟(tpd)典型值230ns,在常规数字逻辑时序中响应及时,可避免信号滞后导致的误操作;
  4. 实用驱动能力:灌电流(IOL)达880μA、拉电流(IOH)360μA,可直接驱动小型负载(如LED指示灯、小型继电器线圈)或级联后续逻辑门,无需额外驱动电路;
  5. 宽温适应能力:工作温度范围覆盖-40℃~+85℃,符合工业级温度标准,可在户外、车间等恶劣环境下稳定运行。

三、封装与功能特性

该器件采用SOP-16贴片封装,体积紧凑(通常尺寸为10.0mm×3.9mm),适合高密度PCB布局;双通道独立工作,每个通道具备触发输入、输出端及定时电容/电阻接口,可通过外接RC网络灵活设置输出脉冲宽度(脉冲宽度由RC参数决定,典型应用中可实现微秒至秒级定时)。

四、典型应用场景

CD4528BM/TR的单稳态功能(输入触发后输出固定宽度脉冲)使其在多个领域发挥作用:

  1. 按键消抖:机械按键按下/松开时会产生数十毫秒的抖动脉冲,通过该器件可将抖动转化为单一稳定脉冲,避免单片机等系统误识别按键操作;
  2. 定时控制:在LED闪烁电路中,可设置固定脉冲宽度实现均匀闪烁;在电机驱动中,可控制电机短时间运转(如自动门开关延时);
  3. 信号整形:对不规则输入信号(如传感器输出的窄脉冲、带毛刺的信号)进行整形,输出标准宽度脉冲,提升后续电路的可靠性;
  4. 工业时序控制:因宽温特性,可用于工业自动化设备的时序逻辑环节(如PLC辅助定时、传感器信号处理);
  5. 低功耗设备:在电池供电的便携仪器(如温湿度记录仪)中,利用超低静态电流延长电池续航时间。

五、兼容性与替换建议

作为40XX系列的标准型号,CD4528BM/TR的引脚功能与其他品牌同型号器件(如TI的CD4528BPWR、ON Semiconductor的CD4528BM)完全兼容,可直接替换,无需修改PCB设计,降低了供应链风险与设计成本。

总结来看,CD4528BM/TR凭借宽电压、低功耗、宽温适应及双通道独立工作等特性,成为数字电路中脉冲定时、抗干扰的高性价比选择,适用于消费电子、工业控制、便携设备等多领域。

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
