74HC(T)112: 带设置和复位功能的双频JK触发器；负沿触发器
74HC/1是高速硅栅CMOS器件并且与低功耗肖特基TTL（LSTTL）引脚兼容。它们符合JEDEC标准No. 7A。
74HC/HCT112是双路负沿触发JK型触发器，具有单独的nJnK输入、时钟（nCP）输入、设置（nSD）和复位（nRD）输入。
设置和复位输入为低电平时，设置或复位输出如函数表所示，不受其他输入处电平的影响。
时钟（nCP）输入为高电平时，可使能nJ输入和nK输入并可接收数据。nJ输入和nK输入可控制触发器的状态变化，如函数表所述。在时钟从高到低转换前的某个建立时间，nJ输入和nK输入必须保持稳定，以进行可预测操作。
输出状态变化由nCP从高到低转换启动。
时钟输入的施密特触发器动作使电路高度容许较缓慢的时钟上升时间和下降时间。
