CD4051BPWR 产品概述
CD4051BPWR 是一款由德州仪器(Texas Instruments, TI)推出的多路复用器/解复用器电路,广泛应用于各种电子设备中,以实现信号选择和路径切换。该器件采用16-TSSOP封装设计,能够满足紧凑布局需求,并在现代电子设备中占有一席之地。
CD4051BPWR 的基本功能是将多路输入信号通过控制信号选择,输出至单一路径,支持1个8:1多路复用器配置。这意味着CD4051BPWR可以接收最多8个输入信号,并通过3个选择控制信号将其中一个信号有选择地传递到输出端。这种特性广泛应用于音频、视频、以及数据通信等领域的信号选择与处理。
电源电压范围:CD4051BPWR 具有3V到20V的单电源供电选项,以及±2.5V到±9V的双电源供电选项,使得它能适应多种不同的电源设计和应用环境。
导通电阻:最大导通电阻为240Ω,且通道间的匹配度(ΔRon)为5Ω,确保了在切换过程中信号损耗最小化,从而提高了信号传输的质量。
频率响应:其-3dB带宽达到20MHz,能够有效地处理高速信号,适用于要求高频信号处理的应用场景。
电流和泄漏:漏泄电流(IS(off))最大值仅为100nA,体现了该器件在关断状态下出色的电源管理能力,确保了在待机模式下的低功耗特性。
温度范围:CD4051BPWR 的工作温度范围深入到-55°C至125°C,适应了苛刻环境条件下的应用,使其适用于工业控制、汽车电子、航空航天等领域。
CD4051BPWR因其灵活的信号选择功能,广泛应用于以下几种场合:
音频切换:在音频设备中,可以用于选择不同的音频源,如在多路音频设备中按需切换,极大改善使用体验。
传感器数据收集:在多通道传感器应用中,CD4051BPWR能从多个传感器中选择特定信号进行处理,使得一台设备可以接入多个外部传感器而不会增加复杂性。
多路复用与解复用:
CD4051BPWR采用16-TSSOP(Thin Shrink Small Outline Package)封装,宽度为4.40mm,符合现代表面贴装技术(SMT),适合高密度电路板布局。其小型化设计不仅能节省空间,还能提高生产效率,便于在自动化生产中应用。
CD4051BPWR 是一款性能稳定、适用范围广泛的多路复用器/解复用器,凭借其优异的电气特性和良好的环境适应性,在电子设计中具有极高的应用价值。其灵活的信号管理能力使得设计师能够在各种项目中有效提升电路性能,是现代电子产品设计中不可或缺的关键元器件之一。利用这一器件,设计者可以实现更为复杂和集成的系统设计,满足不断变化的市场需求。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
