74HC4094DR(LX)串行-并行移位寄存器产品概述

一、产品核心功能与定位

74HC4094DR(LX)是灵星芯微(LX)推出的8位串行转并行移位寄存器,属于4000系列高速CMOS逻辑器件,采用SOP-16贴片封装。其核心作用是将串行输入的数字信号转换为8路并行输出,同时支持三态输出模式,可有效解决单片机/MCU等微控制器IO口资源不足的问题,广泛适用于消费电子、工业控制、通信等领域的信号扩展场景。

二、关键电气参数详解

该器件的电气参数覆盖多场景需求,核心参数如下:

  1. 电压范围:支持3V~15V宽电源电压,兼容3.3V、5V、12V等常见系统电源,无需额外电平转换电路即可适配不同平台;
  2. 工作温度:-40℃~+125℃工业级温度范围,可稳定工作于高低温极端环境,满足户外设备、工业自动化等严苛场景;
  3. 输出特性:8位并行输出均为三态结构,当输出使能(OE)为高电平时,输出端进入高阻态,避免总线冲突,支持多芯片级联共享总线;
  4. 速度性能:基于HC高速CMOS工艺,典型传输延迟仅数纳秒(@5V电源),响应速度快,可满足高频信号转换需求;
  5. 集成度:单芯片集成8位移位寄存器与锁存器,无需额外元件即可实现串并转换,减少系统板级空间占用。

三、引脚与封装说明

74HC4094DR(LX)采用SOP-16贴片封装,尺寸小巧(约10.0×3.9mm),适合自动化贴片生产。主要引脚功能如下:

  • 控制引脚:SER(串行数据输入)、CLK(时钟输入,上升沿触发移位)、STB(锁存使能,高电平锁存并行输出)、OE(输出使能,低电平有效输出);
  • 输出引脚:Q0~Q7(8路并行数据输出,三态结构);
  • 电源引脚:VCC(正电源)、GND(地)。

引脚布局遵循标准SOP-16规范,便于电路设计与PCB布线。

四、典型应用场景

该器件凭借串并转换与三态输出特性,在多个领域有成熟应用:

  1. IO口扩展:单片机(如51系列、STM32)IO口不足时,级联两片可将1个串行口扩展为16个并行IO,用于驱动LED、按键矩阵等;
  2. LED显示驱动:驱动8×8 LED点阵、7段数码管(配合译码器),通过串行传输减少排线数量,简化电路;
  3. 工业控制信号转换:宽温特性适配工业现场(如PLC扩展模块、传感器采集),将多通道串行数据转换为并行信号供处理器处理;
  4. 数据总线扩展:多芯片级联后,通过三态输出共享总线,实现多设备数据传输,避免冲突。

五、使用注意事项

为保证器件稳定工作,需注意以下要点:

  1. 电源连接:必须确保VCC接正电源、GND接地,严禁反接(CMOS器件对反接敏感);
  2. 三态控制:STB(锁存使能)与OE(输出使能)需配合使用,实时更新输出时,需在STB为高时保持CLK稳定,避免数据错误;
  3. 静电防护:HC系列为CMOS工艺,易受静电损坏,操作时需佩戴防静电手环/手套,存放于防静电包装;
  4. 时钟信号:CLK输入需为稳定方波(避免毛刺),推荐上升沿触发,频率不超过器件最大工作频率(典型值25MHz@5V)。

六、产品优势总结

74HC4094DR(LX)相比同类器件,具有以下核心优势:

  • 宽适配性:3V15V电压与-40125℃温度,覆盖消费级与工业级场景;
  • 高集成度:单芯片实现8位串并转换+锁存,减少BOM成本与板级空间;
  • 总线兼容性:三态输出支持多芯片级联,避免总线冲突;
  • 高速响应:HC工艺实现纳秒级延迟,满足高频应用需求;
  • 成熟可靠:4000系列器件经市场验证,稳定性高,灵星芯微提供质量保障。

该器件是低成本IO扩展与信号转换的理想选择,适用于各类需要简化电路、减少IO占用的电子系统。

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.
