DESCRIPTION
The M74HC174 is an high speed CMOS HEX
D-TYPE FLIP FLOP WITH CLEAR fabricated with
silicon gate C

MOS 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.
