GR国睿74HC595是一款**8位串行输入、并行输出(支持串行级联)**的高速CMOS移位寄存器,属于74HC系列逻辑器件。其核心作用是解决微控制器(MCU)IO口资源不足的问题——通过3个控制引脚(串行数据、移位时钟、锁存时钟),实现8位并行信号的输出扩展,同时支持“串行转串行”级联,可灵活扩展至任意位数的IO通道,适配消费电子、工业控制等多场景需求。
74HC595的参数适配主流数字系统,核心指标如下:
74HC595因IO扩展灵活、成本低,被广泛用于:
74HC595的级联是核心优势:每个器件的串行输出端(Q7')直接连接下一级的串行输入端(DS),移位时钟(SH_CP)和锁存时钟(ST_CP)共用,仅需增加级联走线,即可实现任意位数扩展(如16位输出需2个级联)。
使用注意:
GR国睿74HC595相比同类产品,具备:
这款器件是MCU系统IO扩展的经典选择,广泛应用于消费电子、工业控制、智能家居等领域,是工程师实现低成本多通道控制的可靠方案。

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.
