TC7WH04FK,LJ —— 东芝 3 通道反相器(SSOP-8 封装)产品概述

一、产品简介

TC7WH04FK,LJ 是东芝(TOSHIBA)推出的一款低功耗 CMOS 反相器器件,内含 3 个独立反相通道,适用电压范围宽(2.0V 至 5.5V),工作温度覆盖工业级 -40℃ 至 +85℃。器件采用 SSOP-8(厚度约 2.3mm)小型封装,集成度高,便于在空间受限的数字电路中替代分立逻辑或实现信号反相/缓冲功能。

二、主要电气参数

  • 工作电压范围:2.0 V ~ 5.5 V
  • 工作温度:-40℃ ~ +85℃
  • 通道数:3(独立反相器)
  • 静态电流(Iq):典型 20 μA(低功耗)
  • 输入阈值:VIH = 1.5 V(高电平识别),VIL = 0.5 V(低电平识别)
  • 输出电平(在不同 VCC 下典型值):VOH ≈ 1.9 V(VCC≈2.0V);2.48 V(VCC≈3.3V);3.8 V(VCC≈5.0V)
  • 输出低电平:VOL = 440 mV(在规定的 IOL 条件下)
  • 驱动能力:IOH / IOL = 8 mA(典型,可驱动小负载)
  • 传播延迟:tpd = 5.3 ns(VCC = 5.0 V,CL = 50 pF)

三、主要特性与优势

  • 宽工作电压:2.0–5.5V 使器件能在 3.3V、5V 或 2.5V 等系统中使用,便于不同电平系统间的接口设计(需注意输入阈值与被驱动器件的兼容性)。
  • 低静态电流:典型 20 μA,有利于电池供电或低功耗应用。
  • 中等驱动能力:单通道 8 mA 的输出驱动能力适合驱动小型负载、指示灯或作为逻辑级驱动器;若需驱动大负载,建议外加缓冲/驱动器。
  • 快速响应:在 5V、50 pF 负载条件下传播延迟约 5.3 ns,适合中速数字逻辑应用。
  • 小型封装:SSOP-8 有利于 PCB 布局节省空间。

四、典型应用场景

  • 数字逻辑信号反相、逻辑级转换与缓冲
  • MCU 外设信号整形、开关去抖或反相驱动
  • 低功耗便携设备的逻辑接口
  • 小电流指示 LED 驱动(需确认电流限制)
  • 多电压系统中作为简单电平适配(注意阈值匹配)

五、封装与引脚注意事项

  • 封装:SSOP-8(厚度约 2.3 mm),适合 SMT 装配。
  • 引脚功能:典型包含三组输入/输出对及 VCC、GND。布局时应将 VCC/GND 靠近去耦电容,输入端避免悬空或长走线以降低噪声敏感性。

六、设计注意事项与建议

  • 电源去耦:在器件 VCC 与 GND 之间靠近芯片放置 0.1 μF 陶瓷去耦电容,减少瞬态噪声和抖动。
  • 输入电平匹配:VIH = 1.5 V、VIL = 0.5 V,请在系统设计时确认上游驱动器在目标 VCC 下能满足这些阈值,避免中间电平导致不确定状态。
  • 输出驱动与热耗:单通道典型 IOH/IOL 为 8 mA,若并联多通道或驱动较大负载,应评估功耗与可能的电压降。
  • 负载电容影响延迟:较大负载电容会显著增加传播延迟,需根据系统时序余量调整。
  • 电平兼容:在 2.0V 工作电压下 VOH 仅约 1.9V,若下游器件要求更高的输入高电平,请选用合适的 VCC 或闭环方案。

七、选型建议

若目标应用需要低功耗、体积小且支持 2.0–5.5V 的反相器,TC7WH04FK,LJ 是一个均衡的选择。在需更大驱动能力或更严格时序的场合,可考虑功率/速度更高的逻辑器件或外加驱动缓冲。选型时同时评估电源电压、输入阈值匹配、输出驱动与系统时序,以确保可靠工作。

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
