SN74LS175N(芯伯乐XBLW)4位D型触发器产品概述

一、产品核心定位与基本功能

SN74LS175N(芯伯乐XBLW)是一款74LS系列4位D型触发器,专为数字电路中的数据存储、时序控制设计。核心功能包括:4路独立D输入锁存、上升沿同步触发、异步低电平复位,且每个触发器提供互补式输出(Q与非Q),可直接驱动双向负载或满足电平匹配需求。该器件属于高速低功耗TTL逻辑器件,兼容2V~6V宽电压范围,适配多种数字系统平台。

二、关键电气参数详解

2.1 工作电压与功耗

  • 工作电压范围:2V~6V,覆盖商业级(3.3V/5V)与部分低电压系统需求;
  • 静态电流(Iq):1uA,低静态功耗特性,适合电池供电或对功耗敏感的应用场景;
  • 动态功耗:结合传播延迟与时钟频率,满足高速切换时的功耗平衡。

2.2 触发与时序特性

  • 触发方式:上升沿触发(时钟端CLK),仅在时钟上升沿锁存输入数据;
  • 异步复位:低电平有效(CLR端),无需时钟同步即可快速清零所有触发器输出;
  • 时钟频率(fc):83MHz,支持高速数据传输与时序控制;
  • 时序约束:建立时间1ns、保持时间0ns,对输入数据的时序要求宽松,易与其他器件接口。

2.3 动态性能

  • 传播延迟(tpd):17ns@5V、15pF负载,高速切换特性,适合对时序延迟敏感的电路(如高速计数器、寄存器)。

三、封装与引脚配置

该器件采用DIP-16直插封装,引脚功能清晰,便于手工焊接与原型开发,引脚定义(标准74LS175兼容)如下:

引脚号 功能说明 引脚号 功能说明 1 异步复位(CLR,低有效) 9 Q3输出 2 D1输入 10 D3输入 3 Q1输出 11 /Q4输出(非Q4) 4 /Q1输出(非Q1) 12 Q4输出 5 D2输入 13 D4输入 6 Q2输出 14 时钟(CLK) 7 地(GND) 15 电源(VCC) 8 /Q3输出(非Q3) 16 预留/空脚

四、典型应用场景

4.1 数字寄存器

存储4位并行数据,异步复位可快速清零,互补输出支持数据双向传输,适用于微控制器外设数据缓冲。

4.2 数据锁存器

时钟上升沿锁存输入数据,保持至下一个时钟周期,用于地址锁存(如配合SRAM、EEPROM的地址暂存)、显示驱动数据锁存等。

4.3 简单计数器

通过级联或反馈可构成4位二进制计数器,异步复位支持快速清零,适合低速到中速计数场景(<83MHz)。

4.4 时序逻辑控制

作为时序单元,实现脉冲同步、状态机转换等功能,如工业控制中的信号同步电路。

五、环境适应性与可靠性

  • 工作温度范围:-20℃~+85℃,覆盖商业级与工业级应用环境(如室内电子设备、小型工业控制器);
  • 逻辑兼容性:符合74LS系列TTL电平标准,可与其他LS系列器件(如74LS00、74LS138)直接接口,无需电平转换;
  • 抗干扰性:TTL逻辑的噪声容限(典型0.4V),适合电磁环境复杂的应用场景。

六、品牌与选型优势

芯伯乐(XBLW)作为国内专业逻辑器件厂商,SN74LS175N具备以下优势:

  1. 引脚全兼容:与国际品牌SN74LS175N引脚定义一致,可直接替换;
  2. 参数匹配度高:时钟频率、传播延迟等核心参数与标准器件一致,满足设计兼容性;
  3. 成本优势:在保证性能的前提下,提供更具性价比的替代方案;
  4. 封装多样性:除DIP-16外,可提供贴片封装(如SOIC-16)适配自动化生产需求。

该器件以高速、低功耗、宽电压范围为核心特点,广泛适用于消费电子、工业控制、通信设备等领域的数字电路设计。

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
