TC7SZ14FE,LJ(CT) 产品概述

一、概述

TC7SZ14FE,LJ(CT) 是东芝(TOSHIBA)TC7SZ 系列中的单路施密特触发器反相器,专为噪声抑制和信号整形设计。器件工作电压范围宽(1.65V~5.5V),静态电流极低(典型值 2 μA),适合对功耗敏感的便携式和电池供电系统。小型 SOT-553 封装便于在高密度电路板上使用。

二、主要特性

  • 输入类型:施密特触发器(提高噪声容限与输入毛刺免疫)
  • 单通道、单输入反相器结构,使用简单
  • 工作电压:1.65 V ~ 5.5 V,支持低压与常见 3.3V/5V 系统
  • 静态电流(Iq):约 2 μA,低功耗
  • 输出驱动能力:IOH / IOL = ±32 mA(典型),可驱动小功率负载和若干门级输入
  • 传播延迟:tpd ≈ 5.9 ns(在 VCC=5V,CL=50 pF 时)
  • 工作温度范围:-40 ℃ ~ +85 ℃

三、关键电气参数

  • 输入高电平阈值(VIH):1.4 V ~ 3.6 V(随 VCC 变化)
  • 输入低电平阈值(VIL):0.2 V ~ 1.2 V
  • 单通道输入,便于点对点信号整形与抖动滤除
  • 属于 TC7SZ 小型化系列,适合空间受限应用

四、典型应用场景

  • 开关消抖与按键输入整形:施密特型阈值防止抖动触发
  • 低压数字系统的缓冲与电平整形(1.8V/2.5V/3.3V/5V 平台)
  • 传感器信号去噪、脉冲整形和计数前端
  • 便携设备、物联网节点与可穿戴产品中对功耗与尺寸有严格要求的应用

五、设计建议

  • 电源去耦:建议在 VCC 与 GND 之间并联 0.1 μF 陶瓷电容,靠近器件电源脚放置,抑制瞬态噪声与延迟变化。
  • 输入匹配:注意 VIH/VIL 随 VCC 的变化,系统设计时确认阈值与上游电平兼容,保证可靠触发。
  • 输出驱动:虽然输出驱动能力达 ±32 mA,但应避免长时间大电流负载,必要时加缓冲或外部驱动器以降低功耗与发热。
  • 负载电容影响传播延迟:高容性负载会增加 tpd,设计时测量实际负载下的时序是否满足系统要求。
  • 热与布局:SOT-553 为小封装,布局时保证良好散热路径及地线完整性,避免影响稳定性。

六、封装与订购信息

  • 品牌:TOSHIBA(东芝)
  • 系列:TC7SZ 系列
  • 型号:TC7SZ14FE,LJ(CT)
  • 封装:SOT-553(小型封装,适合高密度 PCB)
  • 单通道产品,适用于对空间与功耗有严格要求的应用场合

总结:TC7SZ14FE,LJ(CT) 以其低功耗、宽电压范围和施密特输入特性,适合用于各种噪声敏感和低功耗的数字信号整形场景。在系统设计中注意电源去耦、阈值匹配与输出驱动限制,可充分发挥其优势。

Sourcing availability signal

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
