CD4071BM/TR 为 HGSEMI(华冠)生产的四路二输入或门(4×2-输入 OR Gate),输出带缓冲,属于经典的4000系列 CMOS 逻辑器件。器件推荐工作电压范围为 3V 至 15V(以 VSS 为参考),适合在宽电源范围内使用,特别适用于工业及汽车电子等对供电灵活性要求较高的场合。未使用的输入脚必须接至 VDD、VSS 或与另一输入短接,以避免不确定状态。
(以下为典型阈值与输出电平在不同 VDD 下的参考值)
注意:阈值随 VDD 线性变化,上述数值为典型值,设计时应参考具体数据手册的最小/最大规格并加入裕量。
在推动负载为 50 pF 条件下的典型传播延迟(tpd):
对于高速或大电容负载的场合,应考虑器件的速度限制,必要时采用专用缓冲驱动器或降低负载电容。
SOP-14 封装,标准 14 引脚分配包括 8 个输入、4 个输出、VDD 与 VSS。SOP-14 便于表面贴装,适合中小批量生产与自动化贴片。TR 表示卷带包装,利于 SMT 线上料。
总结:CD4071BM/TR 提供了宽电源范围、低静态功耗和稳健的输出缓冲特性,是在多种应用场景下实现逻辑或功能的可靠选择。有关精确极限值、功耗与时序的最小/最大规格,请参阅完整数据手册以进行最终设计验证。

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.
