General Description
The VHCT74A is an advanced high speed CMOS Dual
D-Type Flip-Flop fabricated with silicon gate CMOS tech-
nology. 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 the Q OUTPUT during the
positive going transition of the CK pulse. CLR and PR
are independent of the CK and are accomplished by set-
ting 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 VCC = 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.
Ordering Information
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
