CD4081BE 是标准 4000 系列 CMOS 器件中的四路两输入与门(quad 2-input AND)。本器件在宽电源电压范围内工作(5V–15V),静态电流低,输出摆幅接近电源轨,适合低功耗逻辑与信号组合场合。HGSEMI(华冠)生产的 CD4081BE 采用 DIP-14 封装,便于面包板和通孔电路板使用。
注:上列阈值为典型值,实际门限与工艺、温度和负载有关,设计时应参考完整规格书中的最小/最大限值。
DIP-14 引脚排列(建议在设计前以实际数据手册为准):
在 5V 工作时,输入阈值(VIH ≈ 3.5V)对传统 TTL 兼容性需注意:TTL 输出高电平若不足 3.5V,可能无法被完全识别为高电平,必要时加上电平转换或上拉。总体而言,CD4081BE 适合与其他 CMOS 器件级联,但与老旧 TTL 器件接口时需验证电平裕度。
结语:CD4081BE(HGSEMI)为通用、低功耗的四路 2 输入与门器件,适用范围广,使用时请以厂家完整数据手册为准并注意输入/输出电平与电源条件的匹配。若需更精确的最小/最大参数或波形实例,我可帮助检索并解析对应数据手册条目。

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.
