TXS0104EDR(LX) 双向电平移位器产品概述
一、产品核心定位与基本属性
TXS0104EDR(LX)是灵星芯微（LX）推出的4通道双向数字电平移位器，专为解决不同电压域系统间的信号桥接问题设计。产品兼容1.65V3.6V低电压域（如ARM、FPGA、低功耗MCU）与2.3V5.5V高电压域（如传统5V单片机、外设），支持双向数据传输，无需额外方向控制，广泛适用于工业、车载、消费电子等跨电压场景。
二、关键参数深度解析
1. 双向通道与自动方向检测
- 4个独立双向通道：同一通道可同时实现发送/接收，无需为每个通道配置方向控制引脚；
- 自动方向识别：信号方向由实际数据流向自动切换（如A端发信号则A→B，B端发则B→A），无需软件配置或硬件控制，简化电路设计。
2. 电压与速率兼容性
- 双电源范围：VCCA（1.65V3.6V）适配1.8V/3.3V低功耗器件，VCCB（2.3V5.5V）兼容5V传统系统；
- 50Mbps数据速率：覆盖SPI（<100Mbps）、I2C（<1Mbps）、UART（<10Mbps）等主流低速/中速接口，满足多数嵌入式系统传输需求。
3. 可靠性设计
- 断电保护：任意电源（VCCA/VCCB）断电时，所有通道自动进入三态高阻，避免反向灌电流损坏前后级器件；
- 工业级温度：-40℃~+105℃工作范围，适配户外、车载、工业控制等恶劣环境。
三、封装与引脚功能说明
产品采用SOP-14贴片封装（14脚贴片式），引脚布局清晰，具体功能如下：
引脚编号 功能说明 备注 1 VCCA 低电压电源（1.65V~3.6V） 2~5 A1~A4 低电压侧信号通道（与VCCA匹配） 6 GND 地 7~10 B4~B1 高电压侧信号通道（与VCCB匹配） 11 VCCB 高电压电源（2.3V~5.5V） 12 OE 输出使能（低电平有效，高则高阻） 13~14 NC 空脚（无需连接）使用提示：若无需高阻控制，OE可直接接GND；电源上电建议先VCCB后VCCA，避免反向电流。
四、典型应用场景
1. 工业控制
- PLC与外设桥接：3.3V ARM PLC连接5V模拟量模块、继电器输出；
- 传感器信号转换：低功耗MCU（1.8V）采集5V工业传感器数据。
2. 车载电子
- 车载MCU与总线交互：1.8V车载MCU连接5V CAN总线收发器、仪表盘；
- 车载外设适配：3.3V车载导航与5V USB充电模块信号转换。
3. 消费电子
- 智能家居：3.3V Wi-Fi模块连接5V继电器、传感器；
- 机顶盒：1.8V FPGA与5V HDMI接口、存储模块桥接。
4. 物联网
- 低功耗节点：1.65V MCU与3.3V LoRa模块、环境传感器双向通信。
五、产品核心优势
- 设计简化：自动方向检测+双向通道，无需额外控制电路，减少PCB布线复杂度；
- 兼容性强：宽电压范围覆盖主流新旧系统，适配1.65V~5.5V全电压域；
- 可靠性高：断电保护+工业级温度，抗冲击、耐恶劣环境；
- 成本优化：SOP-14封装贴片易焊接，批量成本低，适合大规模应用；
- 传输稳定：50Mbps速率无明显信号失真，满足多数数字接口需求。
六、使用注意事项
- 电源去耦：VCCA/VCCB引脚附近各接0.1μF陶瓷电容到地，提升电源稳定性；
- 信号匹配：A端信号电平需与VCCA一致，B端与VCCB一致，避免过压；
- OE配置：系统复位时可拉OE为高，防止误信号传输；
- 温度限制：避免超过-40℃~+105℃，防止器件性能下降。
TXS0104EDR(LX)凭借高性价比、宽兼容、易设计等特性，成为跨电压系统信号桥接的理想选择，可快速适配工业、车载、消费电子等多领域需求。

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.
