HGSEMI CD4040BM/TR 12位异步二进制向上计数器产品概述

一、产品核心定位

CD4040BM/TR是华冠半导体(HGSEMI)推出的12位异步二进制向上计数器,属于高速CMOS逻辑器件。该器件针对工业级应用场景优化,具备宽电压范围、低功耗、高计数速率等特点,可稳定实现脉冲计数、时钟分频、时序控制等功能,是消费电子、工业自动化、通信设备等领域的常用计数核心元件。

二、关键性能参数

该器件的核心性能覆盖计数逻辑、电气特性、环境适应性三大维度,具体如下:

  • 逻辑特性:12位二进制向上计数(方向固定为递增);异步复位(MR)机制(复位无需依赖时钟);时钟触发沿为下降沿(仅高→低跳变时更新计数)。
  • 电气特性:工作电压3V~15V(兼容3.3V、5V、12V主流电源);最高计数速率12MHz(15V供电时);典型传播延迟(tpd)100ns(信号响应快,时序误差小)。
  • 环境适应性:工作温度-40℃+85℃(工业级标准);存储温度-65℃+150℃(便于仓储运输)。

三、封装与引脚功能

CD4040BM/TR采用SOP-16(16引脚小外形封装),引脚布局紧凑,易集成到各类PCB设计中。关键引脚功能如下:

  • 引脚1(MR):异步复位端(高电平有效),MR为高时所有计数输出立即清零(全0),无需等待时钟。
  • 引脚3(CLK):时钟输入端(下降沿触发),仅时钟由高变低时更新计数状态。
  • 计数输出(引脚2、47、915):12位输出(Q1Q12),Q1为最低位(LSB),Q12为最高位(MSB),计数范围04095(2¹²-1)。
  • 电源引脚:引脚8(GND,地)、引脚16(VDD,电源正),需匹配3V~15V供电。

四、典型应用场景

凭借12位计数容量、宽电压兼容及工业级可靠性,该器件广泛应用于:

  1. 时钟分频:将高频时钟(如12MHz)分频为低频信号(12MHz/2ⁿ,n=1~12),用于MCU时钟基准、LED驱动时序等;
  2. 脉冲计数:统计传感器脉冲(流量、编码器),实现流量计量、位置检测;
  3. 频率测量:配合MCU统计单位时间脉冲数,计算信号频率(如1秒计数=频率值);
  4. 工业时序控制:生成多相时序信号,用于流水线工位切换、电机脉冲分配;
  5. 低功耗系统:CMOS工艺低功耗(nW级),适合电池供电的手持计数器、报警器。

五、工作原理简述

CD4040由12个级联T触发器组成,采用异步架构:

  • 计数逻辑:每个触发器仅在时钟下降沿翻转,前级输出作为后级时钟;计数从0开始,每触发一次加1,实现二进制递增;
  • 异步复位:MR高电平时,所有触发器立即清零,与时钟状态无关;
  • 循环计数:12位容量为4096,计数周期为4096个脉冲(0→4095循环)。

六、产品优势与适配性

相比同类器件,CD4040BM/TR具备核心优势:

  • 宽电压兼容:3V~15V覆盖主流电源,无需电平转换,简化设计;
  • 工业级可靠:-40℃~+85℃适应严苛环境,降低现场故障;
  • 低功耗CMOS:静态功耗低,适合电池供电系统;
  • 高集成度:12位计数集成于SOP-16封装,减少PCB占用;
  • 兼容替换:引脚与标准CD4040一致,可直接替换同类器件,便于产品升级。

该器件平衡了性能与成本,是各类计数/分频场景的高性价比选择。

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
