74VHCV244FT(BJ)是东芝半导体推出的8通道施密特触发器缓冲器/线驱动器,属于74VHC高速CMOS系列,专为汽车电子、工业控制等场景设计。该器件集成2组4位单向非反相缓冲器,采用三态输出架构,具备宽电压兼容、抗噪声能力强、高速响应等核心特性,且通过AEC-Q100汽车级可靠性认证,可满足严苛环境下的稳定工作需求。
器件工作电压范围覆盖1.8V~5.5V,既支持低功耗场景下的1.8V/2.5V供电,也兼容传统5V逻辑系统,适配不同电压域的应用需求;静态电流(Iq)仅40μA,待机功耗极低,有助于提升系统能效,尤其适合电池供电或低功耗设备。
输入采用施密特触发器设计,具备明显的滞回特性(典型值约0.8V@5V),可有效抑制输入信号的噪声干扰(如电磁干扰、电源波动导致的边缘抖动),尤其适合处理模拟到数字转换后的信号或易受干扰的数字输入,大幅提升信号稳定性。
输出为三态(高电平、低电平、高阻态),支持多器件共享同一总线,高阻态下可断开自身与总线的连接,避免信号冲突;灌电流(IOL)和拉电流(IOH)均达16mA,可驱动中等负载(如LED、小功率继电器或总线线路),满足典型接口驱动需求。
传播延迟(tpd)仅[email protected]、50pF负载,确保信号传输的高速性,适配高频信号处理场景;工作温度范围为**-40℃~+125℃**,覆盖汽车级环境温度要求,可在极端温差(如发动机舱高温、冬季低温)下稳定运行。
74VHCV244FT(BJ)采用20引脚TSSOP-B薄型小外形封装,引脚间距0.65mm,体积紧凑(约4.4mm×6.4mm),适合高密度PCB布局;封装材料具备良好的耐温、耐湿及抗振动性能,结合AEC-Q100认证,可通过汽车电子严苛的可靠性测试(如温度循环、湿度老化、振动冲击等),确保长期稳定工作。
74VHCV244FT(BJ)的核心优势可归纳为:
该器件凭借上述特性,成为汽车电子、工业控制等领域信号调理与总线驱动的优选方案。

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.
