TD302D232H 产品概述
一 概述
TD302D232H（品牌：YLPTEC/易川）是一款高速双路隔离型RS-232收发器，专为工业级双向串行通信设计。器件集成隔离型DC/DC变换器，可用单电源供电同时实现控制器与RS-232线路间的电气隔离，最大隔离电压可达2500V（隔离等级满足常见工业环境的安全与抗干扰需求），无需外接隔离电源，降低系统复杂度与 BOM 成本。
二 主要规格
- 数据速率：最高可达115.2 kbps（115200 bps）
- 工作电压：3.15 V ~ 3.45 V（单电源供电）
- 静态电流（Iq）：60 mA
- 隔离电压：2500 V（标称隔离能力）
- 工作温度范围：-40 ℃ ~ +85 ℃（工业级）
- 是否静电保护：是（具备 ESD 防护）
- 功能特性：过压保护、内置隔离型 DC/DC 转换器
- 封装：DIP-11（便于插板与原型调试）
三 主要特性与优势
- 集成隔离型DC/DC：内部隔离电源消除了外部隔离电源设计，简化系统布局，节省空间与成本。
- 双路收发功能：支持两个独立 RS-232 通道，适合同时驱动两路串口通信。
- 工业级可靠性：宽温工作范围与较高隔离电压，适用于工业控制、数据采集等严苛环境。
- 保护机制完善：内建过压保护与 ESD 抗扰能力，提高系统抗故障能力与长期可靠性。
- DIP-11 封装：方便工程样机开发与维修替换。
四 典型应用
- 工业自动化与 PLC 串口扩展
- 远程数据采集（RTU）、现场总线网关
- POS、售检票机、仪器仪表的人机通信接口
- 医疗设备与测量设备中需要电气隔离的串口通信场合
五 设计与使用建议
- 电源要求：严格提供 3.15–3.45 V 电源并做好滤波与稳压，避免超出额定范围。
- 隔离区布局：在 PCB 布局时保持主次电路隔离走线与爬电距离，遵循厂家隔离设计建议以保证长期安全。
- 去耦与滤波：尽量靠近芯片放置去耦电容和隔离变换器推荐的外部元件，以降低噪声与提高稳定性。
- 信号完整性：在高波特率与长线缆应用中注意地线与接地方式，合理布线以减少干扰和反射。
- 热管理：静态电流约 60 mA，评估系统功耗与散热环境，必要时采取散热措施。
六 封装与可靠性说明
DIP-11 封装便于手工焊接与快速原型验证，器件在工业温度范围内保持性能稳定。结合其过压与 ESD 保护功能，TD302D232H 是需要电气隔离且注重可靠性的串口设计的理想选择。若需进一步电气参数或应用电路，请参考 YLPTEC 提供的完整数据资料。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
