(3)图9所示为六锁存D型触发器CC40174引脚功能图。CC40174内含6个独立的锁存D型触发器,这6个D触发器共用时钟脉冲端CP和清零端R。当CP=1时数据传输,CP=0时数据锁存。
(3) Figure 9 shows the six latch D-type flip-flop CC40174 pin function diagram. CC40174 contains six independent latch D flip-flop, the six D flip-flop share the clock terminal CP and reset end R. Data transfer when CP = 1, data latch when CP = 0.
