SP232AEN-L/TR 是 MAXLINEAR(迈凌)推出的一款全双工收发器(Full Transceiver),集成两路驱动器与两路接收器,采用 SOP-16 封装,面向需要可靠串行电平转换的嵌入式和工业应用。器件内置电荷泵,可在单一 4.5V5.5V 电源下产生所需的 RS‑232 电平,支持最高 240 kbps 的数据速率,工作温度范围为 0℃+70℃,静态电流仅为 1.5 mA,适合对功耗和尺寸有要求的系统设计。
SP232AEN‑L/TR 将 TTL/CMOS 逻辑电平与 RS‑232 电平进行双向转换。内部的升降压电荷泵在给定的 4.5V~5.5V 电源下生成必要的正负输出电压,使驱动器输出达到 RS‑232 标准电平幅度;接收器对输入的 RS‑232 信号进行电平判决并输出 5V 逻辑电平。两对驱动/接收通道支持独立传输与接收,适合点对点或带有多路串口管理的应用场景。
SP232AEN‑L/TR 采用 SOP‑16 封装,利于批量生产和自动贴装。选型时确认工作电压(4.5V5.5V)、工作温度(0℃+70℃)与所需通信速率(≤240 kbps)匹配;若目标环境温度或 ESD 要求更高,应考虑工业级或增强型器件。
总结:SP232AEN‑L/TR 提供了一个集成度高、功耗低且便于布板的 RS‑232 全双工 2 驱动/2 接收收发器解决方案,适用于多数 5V 嵌入式与工业串口场合。选用与设计时应遵循厂商关于电荷泵电容与电源去耦的推荐,做好 PCB 布局与系统级保护以确保长期稳定工作。

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.
