XD74LS75 4通道D型锁存器产品概述

XD74LS75是信路达(XINLUDA)推出的一款经典74LS系列TTL逻辑器件,定位于数字电路中的并行数据暂存与锁存场景,具备4通道独立处理、互补输出、高速响应等核心特性,兼容DIP-16封装,适配消费电子、工业控制、微处理器系统等多领域需求。

一、产品定位与核心功能

XD74LS75属于电平触发型D型锁存器,核心功能是在使能信号有效时,将4组并行输入数据锁存到输出端,并同步输出原信号与反相信号(互补输出)。与触发器不同,其锁存动作由使能端电平控制(低电平有效):使能有效时,输出跟随输入变化;使能无效时,输出保持当前数据不变,适合需要临时存储、状态保持的数字系统设计。

二、关键参数深度解析

XD74LS75的电气参数严格遵循74LS系列标准,核心性能参数如下:

  • 通道数:4通道并行输入/输出,可同时处理4组独立数据,提升系统并行处理效率;
  • 输出类型:互补输出(Q与Q非),每通道同步输出原信号与反相信号,无需额外反相器即可满足逻辑扩展需求;
  • 工作电压:4.75V~5.25V,覆盖标准TTL逻辑电压范围,适配常规电源系统,电源波动容忍性强;
  • 传播延迟(tpd):27ns,属于高速TTL器件,响应速度满足大多数商用、小型工业设备的时序要求;
  • 时序约束:建立时间20ns(数据需在使能有效前20ns稳定)、保持时间5ns(数据需在使能无效后保持5ns),确保数据可靠锁存,避免亚稳态问题;
  • 工作温度:0℃~+70℃,满足商用级设备的环境适应性需求,可用于常规办公、家电、小型工业控制场景。

三、封装与引脚配置

XD74LS75采用DIP-16双列直插封装,引脚布局与标准74LS75完全兼容,便于原型开发、传统PCB焊接及旧设备升级替换,典型引脚功能如下:

引脚编号 功能描述 引脚编号 功能描述 1 通道1输入(1D) 9 通道3输出(3Q) 2 通道1输出(1Q) 10 通道3输入(3D) 3 通道1反相输出(1Q') 11 通道3反相输出(3Q') 4 通道2输入(2D) 12 通道4输出(4Q) 5 通道2输出(2Q) 13 通道4输入(4D) 6 通道2反相输出(2Q') 14 电源正极(VCC) 7 电源地(GND) 15 使能1(EN1,低有效,控制1-2通道) 8 通道4反相输出(4Q') 16 使能2(EN2,低有效,控制3-4通道)

注:使能端(EN1/EN2)为低电平时,对应通道锁存数据;高电平时保持当前数据。

四、典型应用场景

XD74LS75的功能特性使其适用于多种数字系统:

  1. 并行数据暂存:如键盘输入缓冲(存储按键编码)、LED点阵显示的位数据锁存,避免数据刷新冲突;
  2. 微处理器地址锁存:在8位微控制器(如8051)系统中,锁存低8位地址(与数据总线复用),确保地址稳定;
  3. 逻辑扩展:互补输出可直接驱动与门、或门等逻辑器件,无需额外反相电路,简化硬件设计;
  4. 状态监测:存储系统运行状态(如传感器信号、设备故障码),便于上位机查询或故障诊断。

五、品牌与可靠性优势

信路达(XINLUDA)作为国产电子元器件品牌,XD74LS75具备以下优势:

  • 兼容性:完全匹配标准74LS75的电气参数与引脚布局,可直接替换进口或其他品牌器件,无适配风险;
  • 可靠性:采用成熟TTL工艺,批量生产一致性好,抗干扰能力强,适合长期稳定运行;
  • 供应与成本:国产自主生产,供货稳定,交期短,成本低于进口同类产品,提升系统性价比。

六、总结

XD74LS75作为一款经典74LS系列4通道D型锁存器,兼具高速响应、互补输出、稳定可靠等特点,适配DIP-16封装,广泛应用于消费电子、工业控制、微处理器系统等场景。信路达的国产替代方案不仅满足性能需求,更具备成本与供应优势,是传统数字电路升级或新项目设计的理想选择。

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.
