SN74LS47N(LX)是灵星芯微(LX)推出的经典七段数码管驱动芯片,专为共阳极数码管设计,采用DIP-16直插封装,兼容传统手工焊接、原型开发及标准化PCB设计。该芯片核心功能是将4位BCD码(二进制编码十进制)转换为七段数码管的段驱动信号,无需额外编码电路即可实现0~9数字的清晰显示,是各类数字显示设备的基础核心器件。
SN74LS47N(LX)的电气参数覆盖了宽范围应用需求,核心参数如下:
共阳极数码管完美适配
芯片输出为低电平有效,直接匹配共阳极数码管的阴极驱动逻辑,无需额外添加反相器或电平转换电路,简化电路设计;
宽电压/宽温设计
2V6V工作电压覆盖了从电池供电(如3V纽扣电池)到工业5V系统的全场景;-40℃+125℃宽温范围,可稳定工作于低温环境(如北方户外)和高温环境(如车载仪表舱);
低功耗LS系列优势
采用LS(低功耗肖特基)逻辑工艺,相比普通TTL芯片功耗降低约50%,适合电池供电的便携式设备(如电子钟、计算器);
内置消隐功能
支持灭零输入(RBI) 和灭灯输出(RBO) :当RBI接地时,可实现“0”数字的消隐(如多位显示时的前零消隐);RBO可级联至下一级的RBI,实现多位数码管的联动消隐,提升显示整洁度;
BCD码直接输入
接收4位BCD码(00001001),对应09数字输出,无需复杂的数字编码转换,降低系统开发难度;
DIP封装易调试
DIP-16直插封装便于手工焊接、原型验证,同时兼容标准面包板和PCB插件工艺,适合从实验室原型到量产的全流程开发。
SN74LS47N(LX)凭借稳定可靠的性能,广泛应用于以下场景:
SN74LS47N(LX)作为灵星芯微推出的经典LS系列数码管驱动芯片,以宽电压、宽温、低功耗、适配共阳极数码管 为核心优势,兼顾了可靠性与成本效益,是各类数字显示设备的首选驱动器件。无论是工业级应用的严苛环境,还是消费电子的低成本需求,该芯片都能提供稳定可靠的显示驱动方案。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
