NE555N 是一款广泛使用的时基集成电路,由 HGSEMI(华冠)生产,采用 DIP-8(双列直插封装)形式。这款芯片因其出色的性能和多功能性,成为了模拟和数字电路中不可或缺的元件,广泛应用于定时器、脉冲产生、波形发生器等多种场合。
NE555N 具有以下主要性能特点:
NE555N 可配置为单稳态、双稳态和astable(自激振荡)三种工作模式:
单稳态模式:当触发引脚输入一个负脉冲时,输出引脚会产生一个定宽的高电平脉冲,输出脉冲宽度由外部电阻和电容值决定。在数字电路中,这种模式常用于时间延迟控制。
双稳态模式:NE555N 在此模式下,输出状态可以在高和低之间切换。当触发引脚接收到信号时,输出状态将改变,并保持该状态,直到再接收到信号。此模式常用于开关控制和计数器应用。
自激振荡模式:在此模式中,NE555N 产生连续的方波信号,其频率和占空比同样可以通过外接电阻和电容调节。这种模式非常适合于音频信号生成、电机驱动等应用。
由于其灵活的功能和易于使用的特性,NE555N 的应用涵盖了多个领域,包括但不限于:
NE555N 使用 DIP-8 封装,具有8个引脚,具体引脚配置如下:
NE555N 时基集成芯片是一款简单易用、性能卓越的电子元器件,凭借其多样的工作模式和广泛的应用场景,成为了电子设计中的经典之作。无论是新手电子爱好者还是专业工程师,NE555N 都能提供强大的支持,助力各类创新设计的实现。凭借其高性价比和高适用性,NE555N 在现代电子应用中依然保持着重要地位。

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.
