74HC07M/TR 产品概述

一、产品简介

74HC07M/TR(华冠 HGSEMI)为六通道非反相缓冲/驱动器,输出为开漏(open-drain),适用于需要线与逻辑“有源拉低”或多路汇流(wired-AND/wired-OR)等场合。器件工作电压范围宽(2V~6V),单片包含6位缓冲单元,封装为 SOP-14,工业级温度范围 -55℃~+125℃,适合多种工业与消费类电子设计。

二、主要特性

  • 输出类型:开漏(需外部上拉电阻或上拉网络)
  • 工作电压:2.0V ~ 6.0V
  • 通道数:1 芯片内含 6 位缓冲器
  • 静态电流(Iq):典型 20 μA(空载低功耗,有利于电池供电设计)
  • 传播延迟(tpd):6 ns @ 6V、CL=50 pF(时序随负载与供电电压变化)
  • 封装:SOP-14,易于插装与表面贴装

三、电气与时序要点

74HC07 为开漏输出,逻辑“1”需由外部上拉电阻或电源拉起,上拉电压应与 VCC 匹配且不得超过器件额定电压。传播延迟随 VCC 和负载电容增加而变长,厂家给出参考值为 6 ns(6V、50 pF)。静态电流低,适合低功耗应用,但在输出高电平时功耗由上拉网络决定。

四、典型应用

  • 总线线与多源输出的有源拉低(如多主机通信线)
  • 与开漏/开集电极外设配合实现有线-AND/有线-OR
  • 逻辑信号缓冲与门间驱动(对输入端容性负载隔离)
  • 不能直接驱动大电流负载(如继电器、功率 LED),需配外部晶体管或 MOSFET 驱动

五、封装与可靠性

SOP-14 小型封装便于 PCB 密集布局,工作温度覆盖 -55℃ 至 +125℃,适合严苛环境。设计时应注意器件的最大额定电压与瞬态耐受,避免超过器件极限引起失效。

六、使用建议与布板注意

  • 必装去耦电容:VCC 与 GND 之间 0.1 μF 陶瓷电容,靠近引脚放置,抑制瞬态噪声。
  • 上拉电阻选型:低速可用 10 kΩ,通用应用 4.7 kΩ~2.2 kΩ,高速或大负载可用 1 kΩ 或更小(但会增加功耗)。
  • 上拉电压不得超过 VCC;若需做电平移位,请采用专用电平转换方案。
  • 输出不能作为电流源使用,若驱动大电流负载请外接功率级。
  • PCB 布线尽量缩短关键信号路径,避免长走线产生寄生电容/感应,影响上拉和切换性能。

74HC07M/TR 因其开漏特性、低静态电流与宽工作电压,适合需要可控下拉、总线共享与低功耗缓冲的场景。在选型与设计时,重点关注上拉策略、负载要求与系统时序匹配。

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
