74VHCT74A  
Dual D-Type Flip-Flop with Preset and Clear  
output voltages. This device can be used to interface 3V to  
5V systems and two supply systems such as battery  
backup.  
General Description  
The VHCT74A is an advanced high speed CMOS Dual D-  
Type Flip-Flop fabricated with silicon gate CMOS technol-  
ogy. It achieves the high speed operation similar to equiva-  
lent 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 = 25°C  
High noise immunity: VIH = 2.0V, VIL = 0.8V  
Power down protection is provided on all inputs and  
outputs  
Low power dissipation:  
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  
ICC = 2 µA (max) at TA = 25°C  
Pin and function compatible with 74HCT74  
device destruction due to mismatched supply and input/
