DESCRIPTION

The M54/74HC174 is a high speed CMOSHEXD­TYPE FLIP-FLOP WITH CLEAR fabricated in sili­con gate C2MOStechnology. It has the same high
speed performance of LSTTL combined with true
CMOS low powerconsumption.

Information signals applied to D inputs are trans­fered to the Q outputon the positive goingedge of
the clock pulse. Whenthe CLEARinput isheld low,
the Q outputs are held low independently of the
other inputs. All inputs are equippedwith protection
circuits against static discharge and transient ex­cess voltage.
