概览

MM74HC74A 采用先进的 CMOS 工艺制造，运行速度与 LS-TTL 零部件相媲美。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。74HC 逻辑系列与标准 74LS 逻辑系列在功能和引脚输出方面兼容。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。

  • This product is general usage and suitable for many different applications.
  • 典型传播延迟： 20 ns
  • 宽电源范围： 2-6V
  • 低静态电流： 40 µA，最大值（74HC系列）
  • 低输入电流： 1µA，最大值
  • 10 LS-TTL负载的高扇出
