43、LS175 四上升沿 D 触发器和门电路组成 (4 输入与门选用 74LS21,与非门选用 74HC00),具体电路如图 1 所示。抢答开始时,由主持人清除信号,按下复位开关 S(其连接在 74LS175 的 CLR 端口,实现同步清零) , 74LS175 的输出 1Q4Q 全为 0,所有发光二极管 LED 均熄灭,当主持人宣布“抢答开始”后,首先作出判断的参赛者立即按下开关,例如:1 号选手按下 K1 键,此时 1D 端口被连接到高电平,由 74LS175 时钟的上升沿触发并锁存,使其输出 1Q 为高电平,对应的发光二极管亮,同时 1Q为“0” ,通过与门和与非门送出信号锁住其余三个选手的

44、电路,不再接受其它信号,直到主持人再次清除信号为止。四、方案的实现及单元电路的设计开关阵列(1)该电路由四个单刀双掷开关所组成,每一竞赛者与一组开关相对应。当开关接上端触点时,输出相应 Q 输出端为高电平,反之输出低电平。(2). 四 D 触发器触发锁存电路由四 D 触发器 74LS175 构成,当某一开关首先按下时,触发锁存电路被触发,在输出端产生相应的开关电平信息,同时为防止其它开关随后触发而产生紊乱,最先产生的输出电平变化又反过来将触发电路锁定(3).数码显示管本设计采用的为 LED 数码管,其功能是对最先按下开关的抢答者编号给予显示。四路抢答器主要由四个模块组成,如下图:抢答模块 D
