DESCRIPTION

The M74HCT174 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 (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.
