74HC595M/TR 为 HGSEMI(华冠)推出的 74HC 系列 8 位串行入并行出移位寄存器,具有并行输出三态控制功能,适用于 IO 扩展、数码管/LED 驱动、灯光阵列与微控制器外设接口等场景。器件采用 SOP-16 封装,TR 表示卷带(Tape & Reel)包装,便于 SMT 贴片生产。
自 2023 年 SQ 批次以后该型号已升级为新版本,设计与采购前请务必提前拿到样品做完整验证。建议测试项目包括但不限于:功能一致性测试、时序/最大工作频率、输出电流与电压特性、功耗与温升、三态切换行为、ESD/抗扰性能与焊接回流可靠性。若用于量产,建议进行首批放大试产验证以确认版本差异对系统的影响。
SOP-16 封装适配常见 PCB 布局与手动/自动贴片工艺。注意焊接工艺参数、湿敏等级与储存条件;高输出电流工作模式下请评估功耗分配与散热方案,避免超过 Pd 限制导致器件过热或性能退化。
如需器件详细引脚定义、典型应用电路或完整参数表,请告知,我可提供更详细的技术资料与参考设计建议。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
