DESCRIPTION
The 74VHC174 is an advanced high-speed CMOS HEX D-TYPE FLIP FLOP WITH CLEAR fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.
Information signals applied to D inputs are transfered to the Q outputs on the positive going edge of the clock pulse.
When the CLEAR input is held low, the Q outputs are held low independentlyof the other inputs. Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

■ HIGH SPEED:
   fMAX =175 MHz (TYP.) at VCC = 5V
■ LOW POWER DISSIPATION:
   ICC =4 µA (MAX.) at TA = 25 oC
■ HIGH NOISE IMMUNITY:
   VNIH = VNIL = 28% VCC (MIN.)
■ POWERDOWN PROTECTIONON INPUTS
■ SYMMETRICAL OUTPUT IMPEDANCE:
   |IOH| = IOL = 8 mA (MIN)
■ BALANCEDPROPAGATIONDELAYS: tPLH ≅ tPHL
■ OPERATING VOLTAGERANGE:
   VCC (OPR)= 2V to 5.5V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 174
■ IMPROVED LATCH-UP IMMUNITY
■ LOW NOISE: VOLP = 0.8V(Max.)
