CD4067BMT/TR 产品概述

一、产品简介

CD4067BMT/TR 是华冠(HGSEMI)推出的一款 16 通道模拟多路复用/解复用开关器件,封装为 TSSOP-24。器件支持 16:1 的开关电路结构,可在单片器件内实现 16 路信号的选择与切换,适用于低频模拟信号与一般数字信号的路由与多路复用场景。

二、主要参数

  • 开关类型:16:1 模拟/数字多路复用/解复用
  • 工作电压:3 V ~ 9 V(宽范围单电源供电)
  • 工作温度:-40 ℃ ~ +105 ℃
  • 通道数:16 路
  • 传播延迟 (tpd):约 30 ns
  • 带宽:约 14 MHz(-3 dB 估算)
  • 导通电阻 (Ron):约 470 Ω(典型值或最大值,受电压与温度影响)
  • 封装:TSSOP-24
  • 品牌:HGSEMI(华冠)

三、功能特性

  • 单芯片集成 16 路信号选择功能,节省 PCB 空间与器件数量。
  • 宽电源电压范围,便于与 3.3 V、5 V 等常用系统电源兼容。
  • 在典型条件下传播延迟短、开关速度适中,适合低频到中频信号切换。
  • 双向导通,既可作为多路复用器(MUX),也可用作解复用(DEMUX)或通用模拟开关阵列。
  • 工作温度覆盖工业级范围,适用于工业控制与户外设备。

四、典型应用场景

  • 多通道传感器信号采集与路由(温度、电压、电流传感等)。
  • 音频信号切换与通道选择(受带宽与 Ron 限制,适用于低频音频)。
  • 多路测量仪器的前端选择开关。
  • MCU/FPGA 与多路外设或模拟电路之间的通道复用。
  • 功能选择、电路测试和信号分配场合。

五、设计与使用要点

  • 导通电阻较大(约 470 Ω),会对高阻网络引入显著误差,使用时应评估信号源/负载阻抗及精度要求。对电压测量回路,若要求高精度建议在后端采用缓冲放大器。
  • 带宽约 14 MHz,超出该频段信号将出现衰减与失真,不适合高速数模转换或射频应用。
  • 建议在 VDD 与 VSS(地)之间放置 0.1 μF 陶瓷旁路电容以抑制开关瞬态和电源噪声。
  • 开关的 Ron 随供电电压与温度变化,应在极端工况下验证电路性能。
  • 注意模拟信号电压范围应保持在器件电源 rails 之间,以防止体二极管导通或损坏。
  • 布局时尽量缩短信号路径、分离模拟与数字地、并为高速/敏感通道提供屏蔽或局部去耦。

六、封装与可靠性

TSSOP-24 封装便于 SMD 自动贴装和空间受限设计。器件注明工作温度达到 -40 ℃ 至 +105 ℃,满足大多数工业环境温度要求。焊接工艺应遵循供应商的回流温度曲线,避免过热影响可靠性。

七、选型建议与替代器件

  • 若需更低 Ron 或更高带宽,应考虑专业模拟开关(如带低导通电阻的 CMOS 开关或专用多路复用器)。
  • 对于较低通道数或不同功能(例如双极性模拟开关、三态输出),可参考 CD4051、CD4066 或其它同类器件。
  • 选型时关注 Ron、带宽、供电电压、开启/关闭时间和封装,以匹配目标系统要求。

八、总结

CD4067BMT/TR 是一款适用于多通道信号选择的 CMOS 模拟多路复用器,具有宽电源电压和工业温度范围,适合低频到中频的通用信号切换场合。使用时需注意较高的导通电阻和带宽限制,通过合理的电路设计与 PCB 布局可以在数据采集、音频路由和多路测量系统中发挥良好作用。若有更高性能需求,可在导通电阻与带宽上进行权衡并选择更合适的替代器件。

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
