概览

MM74HCT74 采用先进的硅门极 CMOS 工艺，运行速度与 LS-TTL 零部件相似。它具有标准 CMOS 集成电路的高抗扰度和低功耗，并能驱动 10 个 LS-TTL 负载。此触发器拥有独立的数据、预设、清除和时钟输入，以及 Q 和 Q# 输出。时钟脉冲正向转换期间，数据输入端的逻辑电平被传送至输出。预设和清除输入与时钟无关，通过适当输入端的低电平来完成。74HCT 逻辑系列可与标准 74LS 逻辑系列实现功能和引脚输出兼容。通过将内部二极管箝位到 VCC 和接地，防止所有输入因静电放电受损。MM74HCT 器件适合用作 TTL 和 NMOS 组件与标准 CMOS 器件之间的接口。此类零部件也是 LS-TTL 器件的插件替代品，可用于降低现有设计的功耗。
