NE555N 时基集成芯片产品概述

1. 概述

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。

2. 性能特点

NE555N 具有以下主要性能特点:

  • 工作电压范围:4.5V 到 15V,适应广泛的电源配置。
  • 输出电流:能够提供高达 200mA 的输出电流,适合直接驱动小功率负载。
  • 精度和稳定性:内置温补晶振电路,确保输出频率的稳定性和准确性。
  • 调节方式: 通过外部电阻和电容,可以方便地调节输出脉冲的宽度和周期,非常适合各种应用场合。

3. 工作模式

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。

4. 应用领域

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:

  • 自动化控制:在工业自动化设备中,NE555N 可用作延迟定时器、脉冲控制和开关电源。
  • 音频应用:用于声信号生成和音响设备中的音调控制。
  • LED 灯控:通过频闪或调光效果改进 LED 灯的视觉表现。
  • 计时器与警报器:广泛应用于机械计时器、警报系统中,实现精确的定时和控制功能。

5. 封装与引脚配置

NE555N 使用 DIP-8 封装,具有8个引脚,具体引脚配置如下:

  • 引脚1 (GND):接地引脚,连接到电源地。
  • 引脚2 (TRIGGER):触发输入引脚,用于启动定时器。
  • 引脚3 (OUTPUT):输出引脚,提供时钟脉冲。
  • 引脚4 (RESET):复位输入引脚,用于强制重置定时器。
  • 引脚5 (CONTROL VOLTAGE):控制电压输入,如果不使用则可连接一个电容至地,以滤除高频噪声。
  • 引脚6 (THRESHOLD):阈值输入引脚,用于判断定时器是否结束。
  • 引脚7 (DISCHARGE):放电引脚,负责将电容放电。
  • 引脚8 (VCC):电源引脚,连接外部电源。

6. 结论

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。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
