SN74HC164DTR(XBLW)8位移位寄存器产品概述

SN74HC164DTR是芯伯乐(XBLW)推出的一款高速CMOS串行-并行转换器件,属于74HC系列,专为低功耗、工业级应用场景设计,核心功能为8位串行输入转换为并行输出,可有效扩展微控制器的输入输出(IO)资源,适配多种嵌入式系统需求。

一、产品核心定位与功能

作为8位移位寄存器,SN74HC164DTR的核心作用是将串行数据流转换为并行信号,解决微控制器IO口数量不足的问题。其单芯片集成8位并行输出通道,支持双串行输入(A、B)的逻辑与操作,可实现数据的串行加载与并行锁存,是嵌入式系统中IO扩展、显示驱动、信号转换的常用器件。

该器件兼容标准SN74HC164的功能逻辑,XBLW品牌针对工业应用优化了可靠性,无需额外适配即可替换同类进口器件,降低BOM成本的同时保证性能一致性。

二、关键性能参数解析

SN74HC164DTR的性能参数覆盖了工业级应用的核心需求,关键指标如下:

  • 工作电压范围:2V~6V,兼容3.3V、5V主流嵌入式系统电源,无需电平转换即可适配不同平台;
  • 时钟频率:最高85MHz,支持高速串行数据处理,满足实时性要求较高的场景(如高速IO扩展、数据采集);
  • 工作温度范围:-40℃~+105℃,符合工业级温区标准,可在户外、车载、工业现场等恶劣环境下稳定工作;
  • 位数与集成度:单元件实现8位并行输出,无需多芯片级联即可完成8通道信号转换,简化电路设计;
  • 低功耗特性:基于高速CMOS工艺,静态功耗远低于TTL系列(如74LS164),适合电池供电或低功耗系统。

三、封装与引脚配置

SN74HC164DTR采用SOP-14封装(小外形14引脚贴片封装),体积小巧(引脚间距1.27mm),适合高密度PCB设计,支持自动化贴装,降低生产难度。

引脚功能符合标准SN74HC164定义,核心引脚包括:

  • 串行输入:INA(1脚)、INB(2脚)(逻辑与关系,可并联实现单输入);
  • 时钟输入:CLK(3脚)(上升沿触发移位);
  • 清零端:CLR(9脚)(低电平有效,异步清零);
  • 并行输出:Q0Q7(47脚、10~13脚)(移位后锁存的并行信号);
  • 电源与地:VCC(14脚)、GND(7脚)。

四、典型应用场景

SN74HC164DTR的串并转换特性使其适用于多种嵌入式场景:

  1. 微控制器IO扩展:当MCU(如STM32、51单片机)的IO口不足时,通过SPI或GPIO模拟串行数据,经该器件转换为8个并行IO,控制LED阵列、继电器、按键矩阵等;
  2. 显示驱动:驱动7段数码管(配合译码器)或点阵显示屏的行/列信号,实现多位数显示;
  3. 串行数据并行化:将UART、SPI等串行通信接口的数据流转换为并行信号,供并行ADC、DAC或其他并行设备处理;
  4. 工业控制信号转换:适应-40℃~+105℃的工业环境,用于电机控制、传感器数据采集等场景的信号转换。

五、兼容性与可靠性说明

  1. 引脚与功能兼容:与标准SN74HC164(如TI、NXP等品牌)完全引脚兼容、功能一致,可直接替换,无需修改电路;
  2. 电气可靠性:符合IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)等抗干扰标准,具备高噪声容限(CMOS特性),抗电磁干扰能力强;
  3. 长期稳定性:XBLW品牌采用工业级生产工艺,器件参数一致性好,MTBF(平均无故障时间)满足工业级应用要求。

综上,SN74HC164DTR(XBLW)作为一款工业级8位移位寄存器,以宽电压范围、高速时钟、工业温区等优势,成为嵌入式系统中IO扩展、信号转换的高性价比选择,适配多种场景的功能需求。

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.
