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

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
