CD4538BM/TR 产品概述

一、概述

CD4538BM/TR(HGSEMI 华冠)是一款双路精密单稳态多谐振荡器(dual precision monostable),基于4000B系列工艺。每路为1位单稳态单元,具备独立的触发与复位控制,可实现可重触发与可复位的脉冲产生。控制输入采用内部锁存结构,提供稳定可靠的脉冲宽度控制,适合时序延时、整形、抖动消除与低速计数等场合。器件封装为 SOP-16,提供带卷盘(/TR)等采购形式,工作温度范围为 -40℃ 至 +85℃,工作电压范围 5V ~ 15V。

二、主要特性

  • 双通道单稳态:两路独立工作,互不干扰。
  • 触发沿可选:支持上升沿或下降沿触发(器件提供两种触发输入,可实现不同沿触发方式)。
  • 可重触发、可复位:支持外部重触发与复位输入,控制灵活。
  • 内部锁存控制输入:确保触发/复位响应稳定且不易产生毛刺误触发。
  • 低静态电流:静态电流 Iq ≈ 5 nA(典型),适用于低功耗系统。
  • 宽工作电压:5V~15V,适应多种逻辑电源环境。

三、关键电气参数(典型/测试条件)

  • 工作电压(VCC):5V ~ 15V。
  • 传播延迟 tpd(对触发到输出):300 ns @ 5V,50 pF ;150 ns @ 10V,50 pF;100 ns @ 15V,50 pF。
  • 输出电流能力:灌电流(IOL)与拉电流(IOH)在器件资料中列出为 3 mA;440 μA;1.1 mA(与具体测试电压和负载条件相关,详见完整数据手册)。
  • 输入电容:约 10 pF。
  • 工作温度:-40℃ ~ +85℃。

说明:上述参数为典型或在给定测试条件下测得的参考值。详尽的电流–电压曲线、输入阈值与时序规范请参阅厂商数据手册以获得精确设计依据。

四、功能说明与应用建议

  • 脉冲整形与延时:通过外接电阻与电容设置单稳态的输出脉冲宽度(常见应用为按键去抖、整形短脉冲)。
  • 频率分频与防抖:可作为按键消抖、脉冲展宽器或低速分频器使用。
  • 可重触发应用:在重触发模式下可对高频或间歇触发信号产生固定宽度或延长脉冲。
  • 工业与仪表:适用于需要稳定延时和低静态功耗的控制与测量电路。

五、封装与订购信息

  • 品牌:HGSEMI(华冠)。
  • 器件型号:CD4538BM/TR(/TR 表示卷盘带装,适合贴片生产线)。
  • 封装:SOP-16。
  • 系列:4000B 系列 CMOS 逻辑,具有较强的电压容忍度与低功耗特性。

六、设计与使用注意事项

  • 去耦与稳定性:在 VCC 与 GND 之间建议放置 0.01 μF~0.1 μF 陶瓷去耦电容,靠近器件电源引脚布置。
  • 触发边沿与噪声:控制输入采用内部锁存,但外部接线与开关噪声仍可能引入误触,建议在敏感应用处加滤波或加上小电容。
  • 输出驱动能力:4000B 系列输出电流有限,若驱动较大负载需外接缓冲器或驱动器。
  • 温漂与精度:单稳态脉冲宽度受 RC 元件温度系数影响,关键时序需选用温度稳定的元件或做温度校准。

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
