TMUX1219DCKR 是由德州仪器(TI)推出的一款高性能多路复用器/解复用器IC,专为低电压和高频应用而设计。该器件采用 SC-70-6 封装,具有优异的开关性能和极低的功耗,适合在广泛的应用场景中使用,如通信设备、传感器接口、便携式设备等。
TMUX1219DCKR 是一款单通道、2:1 的开关器件(SPDT),可用于在两条不同信号线之间进行选择。其最大导通电阻为3欧姆,确保信号在切换时能平滑传递,且几乎没有信号衰减。这一特性对于高精度、高保真度的信号处理尤为重要。由于其通道至通道匹配 (ΔRon) 仅为150毫欧,这使得该器件非常适合于多个通道之间的信号交替切换而不造成显著的失真。
TMUX1219DCKR 的工作电压范围为1.08V至5.5V,适应性极强。它能够支持现代许多低电压逻辑电路的要求,尤其是在移动设备和电池供电设备中。其耐压能力使得它适用于各种应用,如维修设备、数据采集系统和传感器网络等。
该器件的最大漏电流(IS(off))仅为5nA,显示出优秀的低功耗性能,特别是在待机模式下非常有用。其电荷注入量为-10pC,意味着在切换过程中对连接信号的影响几乎可以忽略不计,确保了高保真的信号传输。这使得TMUX1219DCKR成为传感器数据采集、精密测量等要求极高的应用中的理想选择。
TMUX1219DCKR 在10MHz下的串扰为-45dB,展现出极好的信号隔离性,适合于多路复用/解复用应用场景,避免了信号之间的相互干扰。同时,其-3dB带宽高达250MHz,证明了其在高频应用中的出色表现,能够处理宽频带信号,满足高数据率的需求。
TMUX1219DCKR 采用表面贴装型(SMT)设计,便于在自动化生产线上进行组装。其标称的工作温度范围为-40°C至125°C,使得该器件能够在各种严酷的环境条件下稳定工作,适合于工业、汽车电子及其余严苛环境的应用。
凭借这些出色的特性,TMUX1219DCKR 广泛应用于包括但不限于以下领域:
TMUX1219DCKR 是一款功能强大、性能卓越的2:1多路复用器/解复用器。它不仅具备宽广的供电电压范围,低功耗设计和低导通电阻,同时在高频应用中的表现也十分出色,能够满足现代电子设备对高性能和高可靠性的需求。它无疑是许多电路设计中的重要选择,能够为设计工程师提供一个稳定且高效的解决方案。
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.
