74VHC74
Dual D-Type Flip-Flop with Preset and Clear
General Description
The VHC74 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 transi-
tion 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 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery backup. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
