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. Protection circuits ensure that 0V to 7V can be applied to the input pins without regard to the supply voltage and to the output pins with VCC = 0V. These circuits prevent device destruction due to mismatched supply and input/output voltages. This device can be used to interface 3V to 5V systems and two supply systems such as battery backup.
Features
 
  • High speed: fMAX = 160 MHz (typ) at TA = 25°C
  • High noise immunity: VIH = 2.0V, VIL = 0.8V
  • Power down protection is provided on all inputs and outputs
  • Low power dissipation: ICC = 2 µA (max) at TA = 25°C
  • Pin and function compatible with 74HCT74
Applications
  • This product is general usage and suitable for many different applications.
