DESCRIPTION
The M74HCT174 is an high speed CMOS HEX
D-TYPE FLIP FLOP WITH CLEAR fabricated with
silicon gate C
2
MOS technology.
Information signals applied to D inputs are
transferred to the Q output on the positive going
edge of the CLOCK (CK) pulse. When the CLEAR
(CLR) 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.
