SN74LVC1G3157DBVR 产品概述

一、产品简介

SN74LVC1G3157DBVR(UMW/友台半导体)是一款CMOS工艺、低功耗的单通道 2:1 模拟开关,采用SOT-23-6小封装,面向便携式与高密度电路中的信号多路选择与切换场景。器件在宽电压范围内工作并具有较低导通电阻与良好的高频特性,可实现对模拟与数字信号的高质量传输与路由。

二、主要电气参数

  • 工作电压:1.65 V ~ 5.5 V,适配单电源系统和多电压平台。
  • 导通电阻 (Ron):典型 12 Ω,低插入损耗,有利于保持信号幅度与带宽。
  • 导通时间 (ton):24 ns;关闭时间 (toff):5.7 ns;传播延迟 (tpd):24 ns。
  • 导通电容 (Con):15.5 pF,影响高频性能与带宽响应。
  • 带宽:约 350 MHz,满足视频、射频及高速模拟信号的基本切换要求。
  • 工作温度范围:-55 ℃ ~ +125 ℃,适用于工业级应用。

三、功能特点

  • CMOS 低功耗设计,静态电流小,适合电池供电设备。
  • 2:1 开关架构,支持快速的通道选择。
  • 双向导通特性(模拟开关类型),可双向传递信号,便于灵活布局。
  • 小体积 SOT-23-6 封装,利于高密度PCB设计与空间受限场景。

四、典型应用

  • 音视频通道切换、模拟信号路由。
  • 通信设备中的多路复用与前端测试切换。
  • 数据采集与仪表系统的输入选择。
  • 便携式与低功耗电子终端中信号路径管理。

五、设计与使用建议

  • 推荐在VCC近旁放置0.1 μF旁路电容以抑制开关瞬态噪声。
  • 输入/输出信号应避免超出电源轨,若存在超限信号需采用限幅或隔离措施。
  • 对于带宽接近器件极限的高速信号,PCB走线应尽量缩短并控制阻抗,必要时在信号线上串入小电阻以抑制反射。
  • 在低温或高温工况下关注Ron随温度变化的影响,关键路径可留充足裕度。

六、封装与订购信息

  • 封装:SOT-23-6,有利于表面贴装与回流焊工艺。
  • 品牌:UMW(友台半导体)。在选型时建议核对制造商/授权分销商提供的最新器件资料,以获取完整的典型曲线与可靠性数据。

本器件以其宽工作电压、低导通电阻与良好高频响应,适合在对功耗与体积有严格要求的系统中用作通用模拟开关与信号选择元件。

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.

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
