DESCRIPTION
The M54HC174 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 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.

■ HIGH SPEED: fMAX = 66MHz (TYP.) at VCC = 6V
■ LOW POWER DISSIPATION: ICC =4µA(MAX.) at TA=25°C
■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28% VCC (MIN.)
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 4mA (MIN)
■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL
■ WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V
