74HC164D(BJ) 产品概述

一、主要特性

74HC164D(BJ) 为东芝(TOSHIBA)生产的高性能 CMOS 串行至并行移位寄存器,属于 74HC 系列。关键参数如下:

  • 功能:串行输入并行输出(8 位移位寄存器)
  • 工作电压:2.0 V ~ 6.0 V
  • 时钟频率 (fc):典型 58 MHz(器件条件下)
  • 每元件位数:8 位
  • 工作温度:-40 ℃ ~ +125 ℃
  • 传播延迟 (tpd):16 ns @ 6 V, CL = 50 pF
  • 封装:SOIC-14

二、功能描述

本器件接受串行数据,通过时钟脉冲将数据移入内部移位寄存器,并在并行输出端提供 8 位数据输出。无锁存输出信号(与带锁存寄存器的 74HC595 区别),适合需要连续移位并并行驱动负载的场合。

三、典型应用

  • LED 阵列驱动与显示行列扩展
  • 微控制器(MCU)输出端口扩展
  • 串行数据接收并并行分发的接口电路
  • 数字信号处理中的移位/延时实现
  • 工业控制与仪表讯号分配

四、引脚与封装注意

SOIC-14 封装利于自动贴装与波峰/回流焊接。未使用引脚应按手册建议处理(上拉或下拉),以避免悬空造成噪声。电源引脚附近建议放置去耦电容(如 0.1 μF)以抑制瞬态电流与振铃。

五、使用与设计建议

  • 时钟信号应保持干净的方波,避免毛刺,必要时加入上升/下降时间控制或缓冲。
  • 负载电容(CL)会影响 tpd 与最大工作频率,设计时按规格表中条件计算裕量。
  • 电源为 2~6 V 范围,若与 TTL/CMOS 其他器件联用,注意逻辑电平兼容性;需要 TTL 兼容输入时可考虑 74HCT 系列替代。
  • 热管理注意:在高温或大负载情况下,检查封装功耗与周边散热条件。

六、兼容与替代

常见替代器件包括功能相近的 74HC164 系列来自其他厂商,或在需要输出锁存功能时选择 74HC595;若需 TTL 电平兼容,可选 74HCT164。

七、采购建议

选购时确认生产批次、原厂/授权分销渠道与器件完整的规格书(datasheet),并核验封装代码(SOIC14)、品名后缀 (BJ) 对应的厂商标识与管脚顺序。量产设计建议先做样片测试以验证时序与电平兼容性。

以上为 74HC164D(BJ) 的概述与工程注意事项,可作为快速选型与电路设计参考。若需详细时序图、电气特性表或参考电路,请告知,我可提供相应要点。

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
