The 74VHC74FT is an advanced high speed CMOS D-FLIP FLOP fabricated with silicon gate C2MOS 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 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.
An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply
voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up.
This circuit prevents device destruction due to mismatched supply and input voltages.
