SN74LXC1T14DCKR 是德州仪器(TI)推出的一款单通道、固定方向的反相电平变换器/缓冲器,适用于 1.1 V 至 5.5 V 范围内的电平转换与信号整形场合。器件采用 SC-70-5 小封装(TI 封装代码 DCKR,带卷包装),单通道设计、推挽输出(CMOS 输出级),具备断电保护功能,工作温度范围为 -40 °C 到 +125 °C,数据速率可达 420 Mbps,适合中高速数据信号的双电压域互连与接口隔离。
在选型时,如需更多通道、双向自动方向控制或更高数据速率,可考虑 TI 其他系列或同类厂商的电平移位器/缓冲器。但若设计要求为:单路反相、可在 1.1 V–5.5 V 范围内任意两侧电压配对、推挽输出且要求断电保护与小体积封装,SN74LXC1T14DCKR 为简洁、低占位的合适选择。
总结:SN74LXC1T14DCKR 提供单通道、固定方向的反相电平转换与推挽输出,覆盖宽电压范围并具备断电保护,非常适合在空间受限且需跨电压域互连的中高速数字系统中作为可靠的接口器件。 若需更详细的电气参数(阈值、电阻、功耗曲线等),建议参考 TI 官方数据手册和器件规范表以完成最终硬件设计。

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.
