SP3223EEY-L/TR 是来自 MAXLINEAR(迈凌)的一款全功能收发器(IC TRANSCEIVER FULL 2/2),在单一芯片上集成了 2 路驱动器和 2 路接收器,适用于串行通信接口的 RS‑232 类应用。器件内置电荷泵,能够在单电源供电条件下产生必要的电平转换,工作电压范围宽(3.0V 至 5.5V),并在工业温度范围内可靠工作(-40℃ 至 +85℃)。器件采用 TSSOP‑20 封装,便于在空间受限的 PCB 上布局与焊接。
SP3223EEY-L/TR 将 TTL/CMOS 逻辑电平与传统串行接口电平进行可靠转换。内部电荷泵电路可在单电源下生成所需的正负电压,从而省去外部 ±12V 电源的设计复杂度。驱动器输出符合 RS‑232 类电平要求,可直接驱动远端串行设备;接收器对输入信号进行电平恢复,输出为 MCU/FPGA 等逻辑电平。典型用途包括点对点串口通信,主/从设备的数据交换,外设控制与调试接口等。
SP3223EEY-L/TR 常见为带胶盘/带卷盘包装,适用于 SMT 自动化生产。封装为 TSSOP‑20,便于在 PCB 上实现高密度布局。型号命名后缀(如 L/TR)通常表示包装与交货形式,量产与样片采购请参考供应商与经销商提供的最新手册与库存信息。
总结:SP3223EEY-L/TR 是一款面向工业与嵌入式串口应用的高可靠性、低成本电平转换收发器。凭借单电源工作、内置电荷泵、良好的温度与静电指标,它能在多种现场环境中替代传统双电源 RS‑232 方案,简化系统设计并提升可靠性。若需具体引脚功能、电气特性曲线与参考电路,请参阅 MAXLINEAR 提供的详细数据手册。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
