74HC273M/TR(HGSEMI / 华冠)是一款高性能的8位D型触发器寄存器,采用74HC高速硅栅CMOS工艺,封装形式为SOP-20。器件内部包含八个上升沿触发的D触发器,具有独立的异步主复位(MR,低有效)输入。器件在时钟上升沿对D输入进行采样并在Q输出反映对应的状态,适用于并行数据暂存、总线隔离、移位缓冲以及微处理器接口等多种数字电路场景。
以上参数为典型条件下参考值,实际系统设计应参考完整器件手册中的极限值和推荐工作条件,并结合PCB走线、电容负载及工作温度进行裕量设计。
总结:74HC273M/TR 是一款可靠、低功耗且时序性能良好的8位上升沿触发D触发器寄存器,适合高速数字系统中的数据暂存与总线控制应用。在具体设计中应依据时序、负载和电源条件选取合适的工作点,保证系统的稳定与可靠。

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.
