XL74HC595 是一款基于 74HC 系列工艺的 8 位串行入并行出移位寄存器,带独立暂存锁存和三态输出控制。核心特性包括:工作电压 2.0V6.0V、工作温度范围 -40℃+85℃、每片 8 位并行输出、输出为三态(可实现总线共享)、在 6V、50pF 负载条件下传播延迟 tpd≈15ns,典型最大时钟频率可达到 30MHz(取决于负载与电源条件)。封装为 SOP-16(150mil),品牌为 XINLUDA(信路达)。
器件包含一个串入式移位寄存器和一个独立的输出暂存寄存器。典型控制信号有串行数据输入(SER)、移位时钟(SRCLK)、暂存时钟/锁存(RCLK)、输出使能(OE,低有效)以及移位清零(SRCLR,低有效)。通过将 Q7'(串出)级联,可方便实现多片并行扩展。三态输出支持总线共享与多模块驱动场景。
XL74HC595 提供 SOP-16 标准封装,适合中小批量手工焊接与表面贴装生产。选型时请确认供应商信路达提供的完整资料与器件批次,下载并参考官方数据手册以获取详细绝对最大额定值、电流限制、典型时序图和 PCB 封装尺寸。若用于工业或高可靠性场景,建议索取器件级可靠性与测试报告。

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.
