ST M74HC174 handbook
Datasheet
M74HC174 is an high speed CMOS HEX D-TYPE FLIP FLOP WITH CLEAR fabricated with silicon gate C2MOS technology. Information signals applied to D inputs are transferred to the Q output on the positive going edge of the clock pulse. When the CLEAR input is held low, the Q outputs are held low independently of the other inputs. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
