74HC14M/TR(HGSEMI 华冠)产品概述

一、概述

74HC14M/TR 是一款六路施密特触发反向器(Hex Schmitt-Trigger Inverter),属于 74HC 系列 CMOS 逻辑器件,由 HGSEMI(华冠)生产并以 SOP-14 封装提供(TR 表示卷带包装)。器件在 2V 至 6V 宽电源电压范围内工作,适合对噪声容忍性和边沿整形有要求的数字信号处理场合。

二、主要参数

  • 输入类型:施密特触发器(带滞回输入)
  • 工作电压(VCC):2.0V ~ 6.0V
  • 静态电流(Iq,典型):40 µA(器件静态消耗,实际受温度与 VCC 影响)
  • 输出电流:拉/灌电流 IOH / IOL = 4 mA(规格下限驱动能力)
  • 输出高电平(VOH,典型):在不同 VCC 下典型值约为 1.9V(VCC=2V),4.4V(VCC=5V),5.9V(VCC=6V)
  • 输出低电平(VOL,典型):100 mV(在指定负载条件下)
  • 传播延迟(tpd):19 ns @ VCC = 6.0V,CL = 50 pF(单级反相器)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:SOP-14(小外形集成封装)

三、产品特点

  • 施密特输入带有明显滞回特性,可有效滤除输入噪声和抖动,对慢上升/下降沿提供可靠的数字化转换。
  • 低静态电流,适用于对功耗敏感的电池供电或便携设备。
  • 宽工作电压范围(2V~6V),兼容不同电压等级的系统设计需求。
  • 中等输出驱动能力(IOH/ IOL ≈ 4 mA),适合驱动小型指示灯、门级输入或作为缓冲、整形单元。
  • 快速响应:在 6V、50 pF 负载条件下单级传播延迟约 19 ns,适用于一般中速逻辑系统。

四、典型应用

  • 信号整形与去抖动(例如机械开关或编码器输入的去抖)
  • 迟缓上/下沿输入的转换与整形,改善门级电路的可靠开关特性
  • 简单振荡器与脉冲整形电路(配合 RC 网络构成方波发生器)
  • 接口缓冲与逻辑反相场合,尤其需要抗干扰能力的数字前端
  • 低功耗便携设备、家用电器控制板、工业控制系统中对噪声敏感的信号路径

五、使用建议与注意事项

  • 电源去耦:在 VCC 与 GND 之间放置 0.1 µF 陶瓷旁路电容,尽量靠近器件 VCC 引脚,抑制电源纹波与瞬态电流。
  • 负载与驱动能力:器件输出能力为约 4 mA,若需驱动较大负载(例如继电器、较大的 LED 或多级 CMOS 输入),建议使用驱动器或缓冲器,避免超出 IOH/IOL 限制。
  • 输入保护与静电:尽管 74HC 系列具有一定抗静电能力,但在装配与调试时仍应注意 ESD 防护,尽量在受控环境中操作。
  • 布局注意:长输入走线或未屏蔽线会增加噪声感应,必要时采用短线、地平面与合适的滤波元件。
  • 温度与功耗:在高温或接近输出最大负载时,器件耗电和响应特性会变化,请在设计中留有裕度。

六、封装与订购信息

  • 型号:74HC14M/TR
  • 品牌:HGSEMI(华冠)
  • 封装:SOP-14
  • 包装形式:TR(卷带包装,适合贴片自动化装配)

备注:文中提供的 VOH、VOL、tpd 等数值为典型/参考条件下参数。最终设计中应参考厂商完整规格书(datasheet)中的典型值与极限参数,并按实际应用条件(温度、负载、电源)进行验证。

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
