SN74LS160N(XBLW芯伯乐)十进制同步计数器产品概述

这款由芯伯乐(XBLW)推出的SN74LS160N,是一款兼容经典LS系列的十进制同步计数器,主打低功耗、高可靠性,适合电子原型开发、工业计数控制等场景。以下从核心定位、参数、引脚、应用等方面详细说明:

一、产品核心定位

SN74LS160N定位于十进制同步向上计数器,核心功能是实现10分频(0-9循环计数),同时支持异步清零和同步预置,属于低功耗肖特基(LS)逻辑器件。相比普通TTL器件,LS系列功耗更低、噪声更小,搭配DIP-16直插封装,兼顾手工焊接便捷性与工业级可靠性,是传统数字电路设计的常用选型。

二、关键电气与功能参数

1. 电气性能参数

  • 工作电压范围:2V~6V,覆盖低电压(如3.3V系统)到标准TTL电压(5V),兼容性强;
  • 计数速率:最大61MHz(典型值),能满足中等速度的数字逻辑需求(如音频分频、高频计数);
  • 传播延迟(tpd):19ns(典型值),时钟到输出的延迟小,响应速度快;
  • 功耗:LS系列典型功耗远低于普通TTL,适合长时间运行场景。

2. 功能参数

  • 计数模式:十进制同步计数(0→1→…→9→0循环),计数方向固定为向上;
  • 触发方式:时钟输入(CLK)采用上升沿触发,输出稳定,无毛刺;
  • 复位/预置:异步清零(CLR引脚低有效,无需时钟同步)、同步预置(LOAD引脚低有效,需时钟上升沿完成);
  • 使能控制:双使能引脚(ENT、ENP),均为高有效,只有同时满足时才计数,方便逻辑扩展。

三、引脚配置与封装说明

SN74LS160N采用DIP-16直插封装,引脚功能与标准LS160完全一致,具体如下(从1脚顺时针排列):

  1. CLR:异步清零(低电平有效,拉低即清零输出Q3-Q0为0000);
  2. CLK:时钟输入(上升沿触发计数);
  3. LOAD:同步预置(低电平有效,下一个时钟上升沿将D0-D3数据置入计数器);
  4. D0:预置数据最低位;
  5. D1:预置数据第1位;
  6. D2:预置数据第2位;
  7. D3:预置数据最高位;
  8. GND:接地;
  9. ENT:计数使能(高有效);
  10. ENP:计数使能(高有效);
  11. Q3:计数输出最高位;
  12. Q2:计数输出第2位;
  13. Q1:计数输出第1位;
  14. Q0:计数输出最低位;
  15. RCO:进位输出(当计数到9时,RCO输出高电平,用于级联扩展);
  16. VCC:电源正极。

四、典型应用场景

  1. 10分频电路:直接作为10分频器使用,输入时钟经过计数后输出1/10频率的信号,适合音频分频、时钟频率降频;
  2. 工业计数控制:如生产线产品数量计数,当计数到预设值(如100)时,通过异步清零或外部逻辑复位,实现批量计数;
  3. 电子钟/定时器:十进制计数适合60进制的十位计数(秒/分的十位),搭配其他计数器可组成完整计时单元;
  4. 仪器仪表计数:如计数器显示模块,将传感器输入的脉冲计数后转换为十进制数字,驱动LED/LCD显示;
  5. 逻辑扩展:通过RCO引脚级联多个LS160,可实现更高位的十进制计数(如2位→00-99,3位→000-999)。

五、工作环境与可靠性

  • 工作温度范围:-20℃~+85℃,覆盖工业级温度区间(非极端环境),适合车间、户外低温场景(如-20℃的仓库);
  • 封装可靠性:DIP-16直插封装耐焊接温度高,手工焊接不易损坏,批量生产时可通过波峰焊;
  • 抗干扰性:LS系列采用肖特基钳位,噪声容限高,适合电磁环境复杂的工业现场。

六、替换与兼容性

SN74LS160N完全兼容TI SN74LS160N、NXP SN74LS160N等主流品牌同型号,引脚功能、电气参数一致,可直接替换无需修改电路设计。此外,也可作为其他十进制同步计数器的替代选型(如CD4017为异步计数,LS160为同步计数,适合对输出稳定性要求高的场景)。

这款芯伯乐SN74LS160N凭借平衡的性能、兼容性和封装优势,成为数字电路设计中十进制计数的经典选型,无论是电子爱好者的原型开发,还是工业设备的批量生产,都能满足需求。

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.
