INVERTING fabricated with sub-micron silicon The output control does not affect the internal gate C2MOS technology. operation of flip-flops; that is, the old data can be This 8 bit D-TYPE FLIP FLOP is controlled by a retained or the new data can be entered even clock input (CK) and an output enable input (OE). while the outputs are off. On the positive transition of the clock, the Q All inputs are equipped with protection circuits outputs will be set to the logic state that were against static discharge and transient excess setup at the D inputs. voltage. While the OE input is at low level, the eight outputswill be in a normal logic state (high or low logic PIN CONNECTION AND IEC LOGIC SYMBOLS
