CD4078BM/TR(HGSEMI 华冠)是一款面向数字逻辑系统的高输入数目 CMOS 器件,集成了正逻辑的 8 输入“或”与“或非(或的反相)”两种功能。该器件属于经典的 4000 系列 CMOS 逻辑家族,旨在为需要合并大量输入或实现复杂组合逻辑的设计提供一个单芯片解决方案,器件封装为 SOP-14(散装或卷带盘装 TR)。
CD4078B 在单个 14 引脚封装内同时提供 8 路输入的 OR(或)输出和其反相输出(NOR),便于在正逻辑设计中直接实现八输入“或/或非”逻辑,减少门级数量与 PCB 占用。该型号是对现有 CMOS 门系列的补充,适用于宽电源范围的低功耗逻辑控制场合。
注:上列阈值为典型值,实际设计应参考厂家完整数据手册中的最小/最大规范并进行实验验证。
总结:CD4078BM/TR 为需要将多路信号进行或/或非合并的设计提供了低功耗、宽电压、集成度高的解决方案。正确的去耦、输入定义与负载匹配能发挥其在工业与消费类电子系统中的稳定与可靠性能。

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.
