TC7WZ74FK,LJ(CT) 产品概述

一、功能简介

TC7WZ74FK 是东芝(TOSHIBA)TC7WZ 系列的一款单位元 D 型触发器,集成置位(SET)和复位(RESET)功能,提供单比特的边沿存储和同步控制能力。器件适用于低压供电系统,常用于寄存、锁存、时序同步等场合。封装为 US8(VFSOP-8-2.3mm),型号后缀为 LJ(CT)。

二、主要参数

  • 类型:D 型触发器(1 位/元件,元件数 1)
  • 工作电压:1.65 V ~ 5.5 V(宽电源范围,便于多电平系统集成)
  • 时钟频率(fc):最高可达 200 MHz(典型高速应用能力)
  • 传播延迟(tpd):4 ns @ VCC=5 V,负载 C_L=50 pF
  • 建立时间(tsetup):1.5 ns;保持时间(thold):1.0 ns
  • 灌电流/拉电流:IOL=32 mA,IOH=32 mA(较强的驱动能力)
  • 静态电流(Iq):10 µA(低静态功耗)
  • 输入电容:3 pF
  • 工作温度范围:-40 ℃ ~ +85 ℃

注:器件为边沿触发结构;请在设计时参考原厂数据手册以确认触发极性(上升沿或下降沿)与异步/同步置位/复位的具体时序定义。

三、性能特点

  • 宽电源范围(1.65–5.5 V):便于在 1.8 V、2.5 V、3.3 V 及 5 V 系统中直接使用,支持电平兼容设计。
  • 高速响应:在 5 V、50 pF 负载条件下,tpd 仅 4 ns,可支持高达 200 MHz 的时钟频率,适合高速寄存与流水线应用。
  • 低功耗:静态电流仅 10 µA,有利于低功耗与电池供电设备。
  • 强驱动能力:IOH/IOL 达 32 mA,可直接驱动较大负载或多个后级输入,减小外部缓冲器需求。
  • 小输入电容(3 pF):对驱动器负担小,有利于维持信号上升/下降速度及时序裕度。

四、典型应用

  • 移位寄存器、并/串转换电路与数据锁存单元。
  • 时钟同步和数据边沿捕获,作为微处理器与 FPGA 的接口缓冲元件。
  • 数据总线暂存、寄存组建中作为基本单元。
  • 低功耗便携设备与工业控制系统中需要高可靠性时序存储的场合。

五、设计与使用建议

  • 时序裕度:tsetup 为 1.5 ns、thold 为 1.0 ns,设计时需保证时钟和数据路径留有足够裕度,以避免亚稳态或误采样。
  • 负载与速度权衡:在接近最高工作频率时应尽量减小负载电容(C_L),并使用合适的走线与去耦策略;负载增大将延长传播延迟。
  • 电源去耦:推荐在器件电源引脚近旁放置 0.1 µF 陶瓷去耦电容,以抑制瞬态电流和保持稳定时钟边沿。
  • 驱动能力利用:IOH/IOL 32 mA 提供较强驱动,但长时间高电流可能增加功耗与发热,必要时采用缓冲或分担负载。
  • 触发极性与置复位逻辑:具体置位/复位为同步或异步、极性为高有效或低有效,请严格参照数据手册接线,避免误操作导致数据丢失。

六、封装与可靠性

  • 封装:US8(VFSOP-8-2.3mm),适合空间受限的表面贴装应用。
  • 工作温度:-40 ℃ 至 +85 ℃,满足工业级温度要求。
  • 品牌与系列:东芝出品,TC7WZ 系列以低功耗、高速 CMOS 逻辑为主,具有较成熟的工艺与可靠性保障。

总结:TC7WZ74FK,LJ(CT) 以其宽电压范围、高速性能、低静态电流和较强输出驱动能力,适合多种数字时序存储与接口场景。为获得最佳性能,请结合系统工作电压、负载条件与时序要求,并参考东芝原厂数据手册进行具体设计与布局。

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
