SGM4T245XTS16G/TR 产品概述

SGM4T245XTS16G/TR 是圣邦微(SGMICRO)推出的一款四位双向三态总线收发器,属于 SGM4T245 系列,采用 TSSOP-16 封装。器件工作电压范围宽(1.2V ~ 5V),静态电流极低(Iq = 24 μA),工作温度覆盖工业级(-40℃ ~ +125℃),适用于低功耗与工业温度环境下的互连与总线隔离需求。

一、主要功能与特点

  • 双向四位数据通道,支持总线主从方向转换,适合双向信号传输与总线仲裁场景。
  • 三态输出结构,支持输出使能以实现总线共享与断开。
  • 宽工作电压:1.2V 至 5V,可在低压核心逻辑与传统 3.3V/5V 系统之间工作。
  • 驱动能力:IOH / IOL = 20 mA,具有较好的驱动/吸收能力,适合驱动中等负载。
  • 低静态电流(24 μA),适合便携与低功耗系统。
  • 工业级温度范围(-40℃ ~ +125℃),满足恶劣环境要求。
  • 封装:TSSOP-16,小尺寸便于密集 PCB 布局。

二、电气性能与时序概览

  • 输出类型:三态(支持总线隔离)。
  • 传播延迟示例:tpd = 143.9 ns @ 1.2 V、CL = 15 pF(在较低供电电压下测得,电源电压提高或负载改变时传播延迟会相应缩短)。
  • 建议在设计时参考厂方完整数据手册以获取不同电压、负载条件下的详细延迟和功耗曲线。

三、典型应用场景

  • 低压至高压逻辑接口(例如 1.2V 核心与 3.3V/5V 外设之间的缓冲/收发)。
  • MCU/FPGA 与外设的数据总线互联与隔离。
  • 多主机总线系统中的总线共享与三态控制。
  • 工业控制、通信设备、存储接口扩展等需要温度与电压兼容性的场合。

四、设计与布局建议

  • 电源去耦:在 VCC 引脚附近放置 0.1 μF(与 1 μF 组合)陶瓷电容,减小瞬态干扰与抑制振铃。
  • 控制端管理:使用明确的方向控制与输出使能逻辑,避免两侧同时驱动造成总线争用。必要时在输出端加入串联阻抗(如 22Ω~100Ω)限制短路电流。
  • PCB 布局:关键信号走线尽量短且成对走线,地平面连续,减少环路面积以降低 EMI。
  • 热管理:在高驱动频率或高环境温度下注意散热与过流保护设计。

五、注意事项与采购信息

  • 在系统上电或热插拔时注意控制 OE(输出使能)与方向控制,保证总线无争用状态。
  • 选择器件时请以厂方数据手册为准,产品型号:SGM4T245XTS16G/TR,封装 TSSOP-16。
  • 如需更高性能(更低延迟或更大驱动能力)或有特殊 ESD、功耗指标要求,请咨询供应商获取对应型号或定制化建议。

总结:SGM4T245XTS16G/TR 将宽电压兼容、低静态功耗与工业级温度特性结合,适合在多电压系统与严苛环境下提供可靠的四位双向三态收发功能。在实际应用中,遵循电源去耦、控制逻辑清晰与合理 PCB 布局的基本原则,可充分发挥该器件的性能优势。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
