74VHCT74A Dual D-Type Flip-Flop with Preset and Clear
July 1997
Revised April 1999
74VHCT74A
Dual D-Type Flip-Flop with Preset and Clear
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.
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 V
CC
=
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.
