General Description
The VHC74 is an advanced high speed CMOS Dual D-Type Flip-Flop fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
   
Features
■ High Speed: fMAX = 170MHz (typ.) at TA = 25°C
■ High noise immunity: VNIH = VNIL = 28% VCC (min.)
■ Power down protection is provided on all inputs
■ Low power dissipation: ICC = 2µA (max.) at TA = 25°C
■ Pin and function compatible with 74HC74
