SN74HC273PW(LX) 8位D型上升沿触发器产品概述

SN74HC273PW(LX)是灵星芯微(LX)推出的一款8位D型上升沿触发触发器,属于高速CMOS逻辑系列(74HC),集成异步复位功能,采用TSSOP-20封装,具备宽电压范围、高速响应、低功耗等核心优势,适用于工业控制、通信、车载等多场景的数字信号锁存与同步。

一、产品核心功能与身份定位

该器件为8位独立D型触发器,核心功能清晰明确:

  • 上升沿触发锁存:仅在时钟(CLK)信号的上升沿(低→高跳变)时,将8位输入数据(D0D7)同步锁存到输出端(Q0Q7);
  • 异步复位清零:通过复位引脚(MR)实现异步操作——无论时钟状态如何,只要MR为低电平,所有输出端立即置0,无需等待时钟沿;
  • 8位并行集成:单芯片整合8个触发器,支持8位数据的同步锁存与异步复位,无需额外扩展单通道器件,简化系统设计。

作为74HC系列兼容器件,其逻辑电平与TTL兼容,可直接与TTL、CMOS电路接口,无需电平转换,适配现有数字系统。

二、关键电气参数及性能优势

SN74HC273PW(LX)的参数设计兼顾高速、低功耗、宽适配性,核心参数及实际优势如下:

1. 宽电压工作范围

工作电压覆盖2V~6V,适配多种电源系统:

  • 2V~3.3V:支持低功耗嵌入式系统(如MCU、FPGA);
  • 5V:兼容传统TTL/CMOS电路,无需电平转换;
  • 6V:满足部分高压应用场景的电压裕量需求,提升系统稳定性。

2. 高速响应性能

  • 时钟频率:最大122MHz,支持高频数字信号的锁存,适配高速数据处理场景;
  • 传播延迟:15ns(@5V、15pF负载),信号从输入到输出的延迟极小,降低系统响应滞后风险;
  • 时序裕量:建立时间4ns、保持时间-2ns(即无需保持,时钟上升沿前数据稳定即可),时序设计容错性强,简化系统时序规划。

3. 低功耗与高驱动能力

  • 静态电流:仅8μA(典型值),待机功耗极低,适合电池供电或低功耗设备(如可穿戴、智能家电);
  • 驱动能力:灌电流(IOL)、拉电流(IOH)均为5.2mA(@5V),可直接驱动LED、小型继电器等中小负载,无需额外驱动电路,减少系统成本。

4. 抗干扰与环境适应性

  • 输入电容:3.5pF(典型值),输入负载小,对前级电路影响弱,提升系统整体稳定性;
  • 宽温范围:工作温度-40℃+125℃,满足工业级(-4085℃)、车载级(-40~125℃)等 harsh 环境需求,适用场景广泛。

三、封装与典型应用场景

1. 封装特点

采用TSSOP-20封装(薄型小外形封装):

  • 体积小(引脚间距0.65mm),适合高密度PCB设计(如小型化设备、多芯片模块);
  • 散热性能良好,可稳定工作在高负载或高温环境,长期可靠性有保障。

2. 典型应用场景

  • 工业控制:PLC、伺服系统中的状态寄存器、数据缓冲器,实现数字信号的锁存与同步;
  • 通信设备:路由器、交换机中的数据帧暂存、时钟同步电路,适配高速数据传输需求;
  • 车载电子:车载中控、传感器接口中的信号锁存,利用宽温特性适配车载环境;
  • 消费电子:智能家电、可穿戴设备中的低功耗数据存储,借助低静态电流延长电池续航;
  • 微处理器扩展:与MCU、FPGA配合,扩展8位并行输出端口,实现多通道数字信号控制(如LED矩阵、继电器组)。

四、品牌与可靠性

灵星芯微(LX)作为国内专注于逻辑器件的厂商,SN74HC273PW(LX)遵循74HC系列工业标准,经过严格的可靠性测试(温度循环、湿度老化、ESD测试等),参数一致性好,适合量产应用,可替代进口同类器件,降低供应链成本。

总结:SN74HC273PW(LX)是一款高性价比的8位D型触发器,兼顾高速、低功耗、宽适配性与宽温特性,适用于多领域的数字信号锁存需求,是工业、通信、车载等场景的理想选择。

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
