General Description
The VHCT74A 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. The signal level applied to the D INPUT is transferred to the Q OUTPUT during the positive going transition of the CK pulse. CLR and PR are independent of the CK and are accomplished by setting the appropriate input LOW.

Features
■ High speed: fMAX 160 MHz (typ) at TA 25qC
■ High noise immunity: VIH 2.0V, VIL 0.8V
■ Power down protection is provided on all inputs and outputs
■ Low power dissipation: ICC 2 PA (max) at TA 25qC
■ Pin and function compatible with 74HCT74
