74VHC00FT(BJ) 产品概述

一、产品简介

74VHC00FT(BJ) 是东芝(TOSHIBA)推出的四路二输入与非门(Quad 2-input NAND),属于 74VHC 高速 CMOS 系列,封装为 TSSOP-14。器件支持宽工作电源范围 2.0V ~ 5.5V,适用于便携式与工业级系统中常见的组合逻辑与接口整合。工作温度覆盖 -40℃~+125℃,适合多种环境应用。

二、主要参数

  • 逻辑类型:与非门(NAND)
  • 通道数:4(每门 2 输入)
  • 工作电压:2.0V ~ 5.5V
  • 静态电流 (Iq):2 µA(典型/静态)
  • 输出下拉电流 (IOL):8 mA
  • 输出上拉电流 (IOH):8 mA
  • 输入高电平阈值 (VIH):1.5 V
  • 输入低电平阈值 (VIL):0.5 V
  • 输出高电平 (VOH):3.94 V(典型测量条件下)
  • 输出低电平 (VOL):360 mV(典型测量条件下)
  • 传播延迟 (tpd):5.2 ns @ VCC=5.0 V, CL=50 pF
  • 封装:TSSOP-14
  • 工作温度:-40℃ ~ +125℃
  • 系列:74VHC

三、关键特性

  • 低功耗:极小静态电流(≈2 µA),适合电池供电系统。
  • 宽电压范围:2.0V 至 5.5V,便于在不同电源域中使用。
  • 高速特性:在 5.0V/50 pF 条件下传播延迟约 5.2 ns,适合中高速逻辑链路。
  • 良好输出驱动能力:IOH/IOL 可达 8 mA,可直接驱动若干逻辑输入或小型负载。
  • 小尺寸封装:TSSOP-14 适合空间受限的 PCB 布局。

四、典型应用

  • 门阵列/胶合逻辑(Glue logic)与基本组合逻辑实现
  • 电平互连与缓冲(注意阈值匹配)
  • 便携式设备与电池供电电路
  • 工业控制与接口电路中的逻辑处理模块
  • 时序和控制信号生成与整形

五、设计与布局建议

  • 为保证稳定工作,电源引脚附近应放置 0.1 µF 陶瓷去耦电容,靠近 VCC 与 GND 引脚焊盘。
  • 尽量缩短关键信号线与输出走线,降低寄生电容与串扰,特别是在高频切换场景下。
  • 输出驱动能力为 8 mA,若驱动更大电流或容性负载,请增加系列限流电阻或使用缓冲器/驱动器。
  • 输入阈值与系统电平应匹配:在低电压工作点(如 2.0V)时,确保系统信号能满足 VIH/VIL 要求。
  • 考虑 ESD 与浪涌保护措施,尤其是与外部信号源或连接器相连时。

六、封装与引脚概述

TSSOP-14 封装小巧,典型引脚配置包括 VCC、GND 以及四组 2 输入和 1 输出(共 12 引脚用于逻辑信号)。具体引脚排列、绝对最大额定值及时序图请参阅东芝原厂数据手册以获取准确信息。

七、注意事项与对比

  • VOH、VOL、VIH、VIL 等参数通常与测试条件(VCC、电容负载、温度)相关,设计时应参考数据手册中的典型值与保证值。
  • 与传统 TTL/LS 系列相比,VHC 系列在功耗和速度上有优势,但输入阈值和驱动特性不同,接口时需注意电平兼容。
  • 在高温或高频率应用中,应关注功耗与热量散布,必要时评估 PCB 散热与布局。

结语:74VHC00FT(BJ) 提供了在宽电压范围内的高速度、低功耗与适度输出驱动能力,是完成通用组合逻辑与胶合逻辑任务的可靠选择。为确保设计可靠性,请以东芝官方数据手册为最终依据。

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
