54ACT109LMQB数据手册TI中文资料规格书

描述 Description

General Description
The ’AC/’ACT109 consists of two high-speed completely in dependent transition clocked JK flip-flops. The clocking operation is independent of rise and fall times of the clock waveform. The JK design allows operation as a D flip-flop (refer to ’AC/’ACT74 data sheet) by connecting the J and K inputs together.Asynchronous Inputs:
  LOW input to SD (Set) sets Q to HIGH level
  LOW input to CD (Clear) sets Q to LOW level
  Clear and Set are independent of clock
  Simultaneous LOW on CD and SD makes both Q and Q HIGH
