CD4051S是国睿(GR)品牌推出的单通道8选1模拟多路选择器/分配器,属于CMOS逻辑系列器件。其核心功能是实现8路模拟/数字信号与1路公共端之间的双向切换,兼具低功耗、宽电压范围、中速切换等特点,适用于多种常规模拟信号处理场景。
CD4051S定位于中速、低成本的模拟通道切换器件,核心功能包括:
CD4051S的参数经过优化,适配常规模拟信号切换需求,核心参数及价值如下:
覆盖主流数字电路电源(3.3V、5V、12V等),无需额外电平转换电路,可直接与单片机、PLC等控制电路兼容。
在10V电源下导通电阻仅80Ω,信号衰减小(对于小信号<1V的应用,衰减可忽略),适合传感器信号、音频信号等低幅度信号切换。
低导通电容降低了高频信号的串扰与损耗,支持kHz~MHz级的模拟信号(如1MHz以下的音频、低速数据信号)传输。
中速切换特性,满足一般数字控制的响应需求(如单片机IO口控制地址输入时,切换延迟不影响系统时序)。
适用于室内常温环境下的工业、消费电子应用,不建议在极端高低温(如-40℃~+85℃)或户外环境使用。
CD4051S采用SOP-16贴片封装,体积紧凑(尺寸约10mm×6mm×1.5mm),适合表面贴装(SMT)工艺,便于小型化电路设计。引脚功能与标准CD4051一致,核心引脚定义:
结合参数特性,CD4051S广泛应用于以下场景:
CD4051S作为国睿品牌的入门级8:1模拟开关,以宽电压、低功耗、中速切换为核心优势,适配常规模拟信号处理需求,在工业控制、数据采集、消费电子等领域具有较高的性价比。其SOP-16封装便于集成,是小型化电路设计的理想选择。

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.
