74VHC393FT(BJ)是东芝(TOSHIBA)推出的高速CMOS逻辑器件,属于双4位二进制异步向上计数器,专为汽车电子、工业控制等对计数速度、宽温适应性及可靠性要求严苛的场景设计。该器件基于VHC(高速CMOS)工艺,兼顾高速性能与低功耗特性,同时通过AEC-Q100汽车级认证,可满足车载及工业环境下的长期稳定工作需求。
作为二进制计数器核心,74VHC393FT(BJ)的参数覆盖高速计数、宽电压范围等关键需求:
采用TSSOP-14B(14引脚薄型小尺寸封装),体积仅为传统DIP封装的约40%,引脚间距0.65mm,适合高密度PCB设计;编带包装(T/R)适配自动化贴装工艺,提升生产效率。
工作温度范围为**-40℃~+125℃**,符合AEC-Q100 Grade 1汽车级标准,可在极端温度(如发动机舱高温、低温环境)下稳定工作;同时具备抗静电(ESD)与抗电磁干扰(EMI)能力,降低复杂环境下的信号干扰风险。

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.
