SN74LVC1G123DCT(LX) 单稳态多谐振荡器产品概述

SN74LVC1G123DCT(LX)是灵星芯微(LX)推出的单通道单稳态多谐振荡器,属于74LVC低电压CMOS逻辑系列,采用TSSOP-8薄型小封装设计,兼具宽电压兼容、低功耗、高驱动能力与强抗干扰特性,可稳定适配消费电子、工业控制、汽车电子等多场景的单脉冲控制需求。

一、核心功能与定位

单稳态多谐振荡器的核心作用是触发后产生单次固定宽度脉冲(脉冲宽度由外接电阻R与电容C参数灵活配置),支持可设置触发沿(上升沿/下降沿),避免多次触发。该器件为单通道设计,精准满足单脉冲控制场景,如按键消抖、时序同步、窄脉冲展宽等需求,无需额外通道扩展,简化系统布局与成本。

二、关键电气特性详解

  1. 宽电压工作范围:支持1.65V~5.5V电源电压,覆盖从1.8V/3.3V低功耗便携设备(如智能手环、物联网节点)到传统5V工业系统的全场景应用,无需电平转换电路,兼容性极强。
  2. 超低静态功耗:典型静态电流仅10μA,即使在持续待机状态下也能大幅降低系统总功耗,显著延长电池供电设备的续航时间,适配对功耗敏感的物联网终端。
  3. 高速响应速度:传播延迟(tpd)典型值5.3ns,在高频系统中可快速响应触发信号,确保时序准确性,避免信号滞后导致的模块动作错位。
  4. 强负载驱动能力:灌电流(IOL)与拉电流(IOH)均达32mA,可直接驱动LED、小型继电器、逻辑门等负载,无需额外驱动芯片,简化电路设计并降低成本。
  5. 工业级宽温范围:工作温度覆盖-40℃~+125℃,可在极端环境(如汽车发动机舱、户外工业传感器)下稳定运行,可靠性符合车载与工业级标准。
  6. 抗干扰输入设计:输入采用施密特触发器结构,具有滞回特性,能有效过滤输入信号中的电磁干扰、信号波动等噪声,大幅降低误触发概率,无需额外滤波电路。

三、典型应用场景

  1. 消费电子按键消抖:机械按键存在10~20ms抖动,通过该器件产生固定宽度脉冲,可消除多次触发,提升遥控器、键盘等设备的操作准确性。
  2. 工业时序同步:工业控制、通信设备中,不同模块的时序需精准同步,该器件可产生精确同步脉冲,确保PLC、传感器等模块动作协调。
  3. 窄脉冲展宽:传感器输出的窄脉冲(如光电传感器短脉冲)可通过外接RC展宽到系统检测所需宽度,便于后续电路处理。
  4. 汽车电子信号处理:适配-40~125℃宽温,可用于车载中控、胎压监测等场景,满足车载环境的可靠性要求。
  5. 物联网低功耗节点:低静态电流特性适合电池供电的智能传感器、低功耗蓝牙设备,延长节点续航。

四、封装与可靠性设计

  1. TSSOP-8封装:薄型小尺寸封装(引脚间距0.65mm,体积约3mm×3mm),适合高密度PCB设计,适配便携式设备、小型模块的空间限制。
  2. 高可靠性工艺:采用工业级CMOS制造工艺,具备强ESD防护能力(符合IEC 61000-4-2标准),抗静电、抗振动性能优异,可长期稳定工作于 harsh环境。

五、品牌与系列背景

灵星芯微(LX)是国内专注于逻辑器件、接口芯片的专业厂商,74LVC系列以“低电压+高速+低功耗”为核心优势,SN74LVC1G123是该系列的单通道单稳态型号,DCT后缀明确TSSOP-8封装,适配量产需求,可替代进口同类器件,降低供应链成本。

该器件凭借多维度优势,成为单脉冲控制场景的高性价比选择,可有效简化系统设计、提升可靠性,覆盖从消费电子到工业级的全场景应用。

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
