SN74HC14N(XBLW芯伯乐)6路施密特触发器产品概述

一、产品核心定位与基本属性

SN74HC14N是XBLW(芯伯乐)推出的6通道施密特触发反相器,属于高速CMOS逻辑器件,兼具HC系列的低功耗、高噪声容限,以及施密特触发输入的信号整形能力。产品采用DIP-14双列直插封装,兼容传统插件电路设计,无需特殊焊接工具即可安装,适配原型开发与批量生产场景。

二、关键电气性能参数详解

该器件的核心参数直接支撑多场景应用能力,具体如下:

  1. 施密特触发输入特性:输入具备滞后电压(VCC=5V时典型值~0.8V),可有效抑制输入信号中的噪声干扰(如传感器波动、电磁串扰),避免误触发——这是其区别于普通反相器的核心优势;
  2. 宽电压工作范围:2V~6V供电,兼容3.3V(MCU主流电压)与5V(传统逻辑电路)系统,无需额外电平转换电路,简化设计;
  3. 超低静态功耗:静态电流仅2μA(远低于普通HC系列的~10μA),适合电池供电的便携式设备(如手持监测仪、低功耗传感器节点),显著延长续航;
  4. 输出驱动能力:灌电流(IOL)可达4mA,可直接驱动小型LED、低功耗继电器线圈;输出高电平(VOH)典型值4.5V(VCC=5V时),低电平(VOL)仅100mV,电平摆幅大,噪声容限高;
  5. 高速传播延迟:传播延迟(tpd)12ns(VCC=5V、CL=50pF),满足高频信号处理需求(如脉冲序列整形、时钟滤波)。

三、封装与引脚配置说明

产品采用DIP-14双列直插封装,引脚布局遵循SN74HC14标准:

  • 引脚16:6路施密特触发输入(IN1IN6);
  • 引脚7:接地(GND);
  • 引脚813:6路反相输出(OUT1OUT6);
  • 引脚14:电源输入(VCC)。
    该封装兼容面包板、通用插座,原型开发时可快速插拔调试,批量生产时可通过波峰焊高效组装。

四、典型应用场景

结合参数特性,SN74HC14N(XBLW)的典型应用包括:

  1. 传感器信号整形:工业现场温度、压力传感器输出的模拟电压(如0~5V),经施密特触发输入整形后,输出稳定数字电平,避免噪声误判;
  2. 低功耗便携式设备:电池供电的手持示波器、环境监测仪,利用2μA静态电流延长续航,同时实现信号整形与逻辑反相;
  3. 电平兼容转换:3.3V MCU输出信号驱动5V逻辑电路时,VCC=5V可直接识别3.3V为高电平,无需额外电平转换;
  4. 脉冲噪声抑制:数字通信链路中,对含毛刺的脉冲信号滤波,输出清晰方波;
  5. 工业控制电路:-40℃~+125℃宽温范围,适配户外控制柜、车载电子等极端环境。

五、环境适应性与可靠性

器件工作温度覆盖**-40℃~+125℃**(工业级标准),可在严寒(北方户外设备)、高温(控制柜内)环境长期稳定运行;同时具备ESD防护能力(典型值>2kV HBM),降低生产与使用中的静电损坏风险。

六、选型与替代参考

SN74HC14N(XBLW)完全兼容原厂SN74HC14N的电气性能与引脚布局,可直接替换进口品牌器件,同时具备成本优势;若需贴片封装,芯伯乐还提供SOP-14版本(型号如SN74HC14DR),满足不同安装需求。

该器件凭借低功耗、宽温、施密特触发等核心特性,成为信号整形、逻辑反相场景的高性价比选择,覆盖消费电子、工业控制、便携式设备等多领域。

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
