SN74LVC1G125DBVR-TP是TECH PUBLIC(台舟电子)推出的74LVC系列单通道三态缓冲器,采用CMOS工艺打造,兼具低功耗、高速响应与宽电压兼容特性,是数字系统中信号缓冲、总线驱动的高性价比选择。
该器件为单向三态缓冲器,核心功能是实现信号的“缓冲-驱动-隔离”:通过使能端(OE)可将输出切换至高阻态,支持多器件共享同一总线(避免信号串扰),或实现不同模块间的信号隔离。作为74LVC系列成员,其平衡了“低功耗”与“高速性能”,适配小尺寸、低功耗的系统设计需求。
支持1.65V~5.5V工作电压,覆盖当前主流逻辑电平(1.8V、3.3V、5V),无需额外配置电平转换电路,可直接对接MCU、FPGA、传感器等不同电压域的器件,简化系统设计流程,降低BOM成本。
灌电流(IOL)与拉电流(IOH)均达24mA,双向驱动能力均衡,可有效驱动中等负载(如50pF电容负载),确保信号上升/下降沿无明显失真,满足多数数字系统的信号完整性要求。
静态电流(Iq)仅2μA,待机或低负载状态下功耗极低,尤其适合电池供电的便携式设备(如智能手环、蓝牙耳机),可显著延长设备续航时间。
在5.0V供电、50pF负载条件下,传播延迟(tpd)仅2.6ns,响应速度快,可支持高频信号(如高速数据总线、时钟信号)传输,避免时序错误。
工作温度覆盖**-40℃~+125℃**,符合工业级器件标准,可适应车间高温、户外低温等极端环境,保证恶劣条件下的稳定工作。
该器件采用SOT-23-5超小型贴片封装,尺寸仅约2.9mm×1.6mm,可大幅节省PCB布局空间,适配智能穿戴、微型传感器等对体积要求严格的产品。
品牌方面,TECH PUBLIC(台舟电子)是专注于逻辑器件、接口器件的专业厂商,产品经过可靠性测试,满足工业级应用的品质要求。
如智能手机、智能手环、蓝牙耳机等,低功耗(2μA静态电流)与小封装(SOT-23-5)可适配设备的小型化、低功耗需求,实现信号缓冲与总线共享。
如PLC(可编程逻辑控制器)、传感器节点、电机驱动模块等,宽温范围(-40℃~+125℃)适应工业现场极端温度,高速响应满足实时控制信号传输。
如路由器、交换机、无线基站等,高速传播延迟([email protected])支持高速数据总线调理,宽电压范围适配不同通信芯片的电平需求。
如车载传感器、仪表盘控制模块等(适配部分汽车级应用场景),实现信号缓冲与隔离,避免电磁干扰。
SN74LVC1G125DBVR-TP的核心优势可概括为:
该器件凭借上述特性,成为多领域数字系统中信号调理的高性价比选择。
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.
