东芝74VHC245FT(BJ,K)是一款基于高速CMOS(VHC)工艺的8位三态双向收发器,专为数字电路中多通道信号双向传输与总线共享设计,兼具低功耗、宽电压兼容、高速传输等核心特性,广泛适配工业控制、车载电子、消费电子等多种应用场景。
作为74VHC系列的经典收发器产品,74VHC245FT(BJ,K)的核心功能是实现8路数字信号的双向传输切换,支持三态输出(高电平、低电平、高阻态),可有效解决多器件共享总线时的信号冲突问题,是数字系统中总线扩展、接口转换的关键组件之一。
工作电压范围覆盖2V~5.5V,兼容三大主流电压域:
灌电流(IOL)与拉电流(IOH)均为8mA,具备中等负载驱动能力,可直接驱动数字逻辑门、小型显示模块等负载,无需额外驱动电路,降低系统成本。
采用TSSOP-B-20薄型小尺寸封装,引脚数20,封装体积相比DIP封装节省约70%空间,适合小型化产品(如智能手表、微型控制器)及高密度PCB布局,贴合现代电子设备的小型化趋势。
工作温度范围为**-40℃+125℃**,覆盖工业级(-4085℃)与部分车载级(-40~125℃)温度要求,可稳定工作在高低温交替的工业现场、车载环境(如发动机舱、仪表盘)等恶劣场景,可靠性突出。
作为东芝半导体的成熟产品,74VHC245FT(BJ,K)依托东芝的工艺技术优势:
综上,东芝74VHC245FT(BJ,K)凭借宽电压兼容、高速低功耗、宽温工作等特性,成为数字系统中多通道双向信号传输的优选器件,适配各类对性能、可靠性有要求的应用场景。

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.
