74LVC1G14GV是台舟电子(TECH PUBLIC)推出的单路施密特触发非门,属于74LVC系列通用逻辑器件。该芯片针对低功耗、宽电压兼容、抗噪声场景设计,以超小型SOT-23-5封装实现单通道逻辑功能,是便携式设备、工业控制、汽车电子等领域的高性价比逻辑解决方案。
该芯片的电气参数覆盖宽电压、低功耗、高驱动等核心特性,具体如下:
支持1.65V~5.5V的电源电压范围,兼容1.8V、2.5V、3.3V、5V等主流逻辑电平,无需额外电平转换电路,可直接适配不同电压系统。
静态电流(Iq)仅10μA,远低于普通逻辑门的功耗水平,适合电池供电的便携式设备(如可穿戴、IoT传感器节点),有效延长续航时间。
灌电流(IOL)和拉电流(IOH)均达24mA,可直接驱动中等负载(如小型LED、继电器线圈、逻辑门级联),无需额外驱动芯片,简化电路设计。
具备输入阈值滞回特性(上升沿与下降沿阈值存在差异),能有效抑制输入信号的噪声干扰(如电磁干扰、信号波动),避免误翻转,提升系统可靠性。
不同电压下的传播延迟(tpd)表现优异:
工作温度覆盖**-40℃~+125℃**,符合工业级器件标准,可适应户外、车载、工业现场等恶劣环境。
输出高电平(VOH)和低电平(VOL)与主流逻辑电平匹配:
采用SOT-23-5超小型表面贴装封装,尺寸紧凑(约2.9mm×1.6mm),节省PCB空间,适合小型化模块设计。引脚功能如下:
引脚编号 功能 说明 1 IN 输入引脚(施密特触发) 2 OUT 输出引脚(非门逻辑) 3 GND 电源地 4 NC 空脚(无连接) 5 VCC 电源正(1.65V~5.5V)74LVC1G14GV的特性使其适用于多种领域:
74LVC1G14GV是一款高性价比单路施密特触发非门,兼顾宽电压、低功耗、高驱动、抗噪声和小封装特性,可满足便携式设备、工业控制、汽车电子等多场景的逻辑控制需求,是台舟电子74LVC系列中的经典单通道逻辑器件。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
