M74HC174 HEX D-TYPE FLIP FLOP

The 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 DIP SOP TSSOP ORDER CODES PACKAGE TUBE DIP SOP TSSOP M74HC174B1R M74HC174M1R T&R M74HC174RM13T.
