74VHCT74A -- Dual D-T May 2008 74VHCT74ADual D-Type Flip-Flop with Preset and Clear Features General Description ype F n High speed: fMAX = 160MHz (Typ.) at TA = 25°C The VHCT74A is an advanced high speed CMOS Dual n High noise immunity: V D-Type Flip-Flop fabricated with silicon gate CMOS tech- IH = 2.0V, VIL = 0.8V lip nology. It achieves the high speed operation similar to n Power down protection is provided on all inputs and -Flop with Preset and Clear outputs equivalent Bipolar Schottky TTL while maintaining theCMOS low power dissipation. The signal level applied to n Low power dissipation: ICC = 2µA (Max.) at TA = 25°C the D INPUT is transferred to the Q OUTPUT during the n Pin and function compatible with 74HCT74 positive going transition of the CK pulse. CLR and PRare independent of the CK and are accomplished by set-ting the appropriate input LOW. Protection circuits ensure that 0V to 7V can be applied tothe input pins without regard to the supply voltage and tothe 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 3Vto 5V systems and two supply systems such as batterybackup.
