HGX3485EIDQ/TR 是华冠 (HGSEMI) 面向工业通信设计的一款 3.3V 供电半双工 RS-485/RS-422 收发器。芯片集成一路驱动器和一路接收器,支持高达 12 Mbps 的数据速率,链路最多可挂接 256 个节点,工作温度范围 -40℃ 至 +85℃,适用于严苛环境下的长线差分数据传输。器件封装为 DFN-8-EP(3x3),适合高密度电路板设计与散热需求。
DFN-8-EP(3x3) 小尺寸封装利于高密度布线与焊接可靠性。芯片带有外露散热焊盘(EP),建议在 PCB 设计时在底层加铺铜并过孔连接,提高散热和接地性能。常用引脚包括差分 A/B、RE/DE 或单使能控制引脚、电源 VCC 与地 GND、以及接收器输出 RO 和驱动器输入 DI。
HGX3485EIDQ/TR 提供卷带/托盘等常用包装形式,适合贴片生产。若需样片、评估板或详细数据手册(电气特性曲线、典型应用电路、引脚排列图),请联系华冠官方技术支持或当地授权代理,获取最新版规范与设计参考资料。
以上为 HGX3485EIDQ/TR 的产品概述,若需进一步的引脚定义、电气特性表或参考设计原理图,我可以根据具体需求提供更详尽的资料。
Request for quote
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.
