XL74LS00(信路达 XINLUDA)为经典的 74LS 系列四路二输入与非门(Quad 2‑input NAND)逻辑芯片,封装为 SOP‑14。器件在标准 TTL 电源 5V(4.75V~5.25V)下工作,适用于常规数字逻辑控制、门电路构成与低速数字系统的逻辑实现。
74LS00 属于低功耗肖特基 TTL(LS)家族,输出高电平能提供的电流有限(IOH 约 400 μA),因此在做高电平驱动或与 CMOS 直接接口时要注意电平匹配。下拉能力较强(IOL = 8 mA),适合拉低多个 TTL 输入。由于 VOH 较接近 TTL 规范下限,级间扇出建议按规范控制,典型扇出约为 10(视具体输入电流而定)。
SOP‑14 表面贴装封装,便于自动贴片与波峰/回流焊接。信路达提供出厂前的静电防护与基本质量检验,适合商业与一般工业类应用场景。长期可靠性建议参考供应商的完整规格书与应力测试报告。
型号:XL74LS00(信路达 XINLUDA),封装 SOP‑14。若需替代,可选用其他厂家兼容的 74LS00 系列器件或更现代的 CMOS 等效(如 74HC00/74HCT00,若需更低功耗或更高输入阻抗时使用 HCT 可保持 TTL 兼容电平)。采购时请确认温度等级、批次与放行文件以保证一致性。

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.
