XL8574T 是信路达(XINLUDA)推出的一款基于 I2C 总线的 8 位 I/O 扩展器,可为微控制器提供额外的通用数字口。器件采用 SOP-16-300mil 封装,工作电压宽范围 2.3V 至 5.5V,工作温度范围 -40℃ 至 +85℃,适用于工业级与消费类电子设备的 GPIO 扩展需求。
XL8574T 通过 I2C 总线向主控提供 8 路可编程的数字口,既可作为输入也可作为输出使用。由于输出为开漏结构,外部电路通常需要上拉电阻以获得逻辑高电平。中断引脚在检测到输入引脚状态变化时拉低,提示主控进行 I2C 读取或处理,能够降低主控的轮询开销与功耗。

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.
