SN74LS112N（芯伯乐XBLW）双下降沿JK触发器产品概述
一、产品基本信息
SN74LS112N是芯伯乐（XBLW）推出的74LS系列数字逻辑器件，属于双1位下降沿触发JK触发器，采用DIP-16双列直插封装，集成2个独立的1位JK触发器单元，输出为互补型（Q与Q非），是经典数字电路中实现时序逻辑功能的核心器件之一。
二、核心功能与工作特性
该器件具备JK触发器的典型操作逻辑，核心特性如下：
- 功能覆盖：通过时钟（CLK）、置位（S）、复位（R）、J/K输入，实现保持、翻转、置位、复位四种基础时序功能；
- 触发方式：采用下降沿触发时钟信号，仅在时钟脉冲从高电平到低电平跳变时更新输出状态，抗干扰性强；
- 异步控制：置位（S）和复位（R）为异步操作，无需等待时钟信号即可直接改变输出状态，响应速度快；
- 互补输出：每个触发器单元提供Q和Q非两个互补输出端，可直接为后续电路提供相反逻辑电平，简化外围设计；
- 时钟带宽：最大时钟工作频率达66MHz，满足中等速率数字系统的时序要求。
三、关键电气性能参数
SN74LS112N的电气参数经过严格测试，核心指标明确：
- 工作电压：2V~6V，兼容低功耗与常规电源系统；
- 传播延迟：在6V电源、50pF负载条件下，tpd为37ns，保证信号传输快速性；
- 灌电流能力：输出低电平时最大灌电流（IOL）为5.2mA，可驱动中等负载（如LED、小型逻辑门）；
- 建立时间：J/K输入信号需在时钟下降沿前7ns稳定，确保数据可靠锁存；
- 温度范围：-20℃~+85℃，适应工业级与商业级环境的温度变化。
四、封装形式与典型应用场景
4.1 封装说明
采用DIP-16双列直插封装，引脚间距2.54mm，适合面包板实验、插件式PCB焊接，便于手工安装与调试，是原型开发与小批量生产的理想选择。
4.2 典型应用
该器件广泛应用于数字逻辑系统的时序控制与状态存储，常见场景包括：
- 脉冲计数：级联多个单元实现二进制计数（如2位、4位计数器）；
- 分频器：利用翻转功能实现2分频、4分频，将高频时钟转换为低频信号；
- 按键防抖：结合电容电阻实现按键信号防抖，消除机械抖动；
- 状态锁存：存储工业控制、消费电子中的临时状态（如设备启停、传感器触发信号）。
五、可靠性与兼容性
SN74LS112N基于74LS系列低功耗肖特基工艺，具备以下优势：
- 低功耗：相比传统TTL器件功耗显著降低，适合电池供电或功耗敏感场景；
- 兼容性：与其他74LS系列器件引脚兼容，可直接替换同类产品，降低设计成本；
- 稳定性：宽电压、宽温度范围设计，以及明确的参数规范，保证长期工作可靠性。
该器件凭借成熟的74LS工艺、明确的电气参数与灵活的应用场景，成为数字电路设计中时序逻辑功能实现的经典选择，适用于原型开发、小批量生产及工业控制等领域。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
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.
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.
