PCA9548AD,118 是恩智浦(NXP)推出的多路 I²C/SMBus 转换开关(I²C 多路复用器),封装为 24-SO 表面贴装型,常用于在单一主机总线上选择或隔离多个从机总线。器件通过写入控制寄存器来选择通道,支持灵活的总线划分与地址冲突解决。型号后缀 “,118” 通常表示特定的包装与供货代码(例如卷盘包装)。
PCA9548A 系列通过一个可写入的控制寄存器控制最多八个下游通道(各通道对应一个位),可以同时打开一个或多个通道以将主总线与选定的从总线连接或隔离。每个通道在逻辑上隔离下游设备,从而解决从设备地址冲突、减小总线电容并提高系统鲁棒性。器件为开漏总线结构,需在每个总线侧配置上拉电阻。
PCA9548AD,118 适合需要扩展或隔离 I²C/SMBus 从设备的中高端嵌入式系统,尤其在传感器阵列、工业控制和多外设管理场景中能显著简化硬件与固件设计。使用前建议参阅 NXP 官方数据手册与器件选型表,确认所购型号的准确工作电压与引脚定义,并按数据手册推荐的上拉电阻与 PCB 布局规范完成设计。

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.
