SN74LVC1G00DBVR 产品概述

一、概述

SN74LVC1G00DBVR 是一颗单路二输入与非门(2-input NAND),属于 74LVC 系列低压高速逻辑器件。该器件工作电压范围宽(1.65V–5.5V),静态功耗极低,且具有较强的输出驱动能力,适合电平兼容要求严格、对功耗和尺寸有要求的便携与嵌入式应用。此处描述基于 UMW(友台半导体)提供的规格参数,封装为小型 SOT-23-5 便于空间受限的电路板设计。

二、主要特性

  • 逻辑类型:二输入与非门(NAND)
  • 系列:74LVC(低压、低功耗、兼容TTL/CMOS混合系统)
  • 工作电压:1.65 V ~ 5.5 V(单电源)
  • 静态电流(Iq):典型 10 μA(静态/待机条件下极低)
  • 输出驱动能力:IOH / IOL = ±32 mA(强输出驱动,可直接驱动较大负载或若干输入)
  • 传播延迟(tpd):约 10 ns(在 VCC = 5 V、CL = 15 pF 条件下)
  • 工作温度范围:-40 ℃ ~ +105 ℃
  • 封装:SOT-23-5(小封装,5 引脚)

三、电气性能要点(关键参数)

  • 输入阈值(VIH):典型 1.7 V(具体阈值随 VCC 而变化,符合 LVC 系列输入特性)
  • 输出高电平(VOH)、输出低电平(VOL):在不同 VCC 与负载工况下器件的 VOH/VOL 测试结果存在差异,典型示例数据包括:
    • VOH:4.00 V、2.15 V、2.73 V、1.47 V、1.64 V(对应不同 VCC 与负载条件)
    • VOL:350 mV、200 mV、10 mV、110 mV、110 mV(对应不同 VCC 与负载条件) 说明:以上 VOH/VOL 为多组测试条件下的测得值,实际电平取决于供电电压、输出负载(IO)以及测试条件。器件在额定驱动电流(如 32 mA)时仍能维持较低的输出低电平与可接受的输出高电平。
  • 输入通道数:2(A、B)
  • 静态/动态特性适配快逻辑切换,适合中高速数字电路。

四、引脚与封装(SOT-23-5)

SOT-23-5 五引脚封装,典型引脚功能如下(实际引脚分配请参照器件引脚图):

  • VCC:电源正极(1.65 V ~ 5.5 V)
  • GND:地
  • A、B:两个输入端
  • Y:输出端 该小尺寸封装便于节省 PCB 面积,适合便携设备和高密度板级集成。

五、典型应用场景

  • 电平转换与接口缓冲(与非门常用于实现简单逻辑或作为组合逻辑单元)
  • 低功耗便携设备、手持终端和消费电子
  • 工业控制与汽车电子(在-40 ℃ 至 +105 ℃ 温度范围内可靠工作)
  • 时序逻辑、脉冲整形和门控控制电路
  • 替换或扩展 TTL/CMOS 混合系统中的逻辑功能

六、使用建议与注意事项

  • 电源旁路:为保证高速切换时电压稳定,建议 VCC 靠近器件引脚放置 0.1 μF 陶瓷去耦电容。
  • 布局与走线:输出驱动大电流(最高可达 32 mA)时,应注意走线宽度和回流路径,避免电压下降与 EMI 问题。
  • 热管理:虽然静态功耗低,但在频繁切换或驱动大电流时需关注局部发热,必要时评估 PCB 散热设计。
  • 输入与输出保护:若用于与更高电压系统直接接口,需注意输入保护与钳位,防止超出器件最大额定电压。
  • 兼容性:LVC 系列输入对 TTL 电平具有良好兼容性,但在低 VCC(接近 1.65 V)工作时,逻辑容限应按规格评估。

七、小结

SN74LVC1G00DBVR(UMW 版本)是一款面向低压和高密度应用的单通道二输入与非门,具有宽电源范围、低静态电流和较强的输出驱动能力。SOT-23-5 封装适合空间受限场合,-40 ℃ 至 +105 ℃ 的工作温度覆盖工业级应用。设计时注意旁路、电源完整性与走线即可在多种嵌入式与接口场景中获得可靠的逻辑功能表现。若需更详细的引脚图、绝对最大额定值和完整电气特性曲线,请参考器件的正式数据手册。

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.
