DESCRIPTION
The M74HC174 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 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.

PD
is defined as the value of the IC's internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. I
