speed 3.3V applications; it can be interfaced to 5V
signal environment for inputs.
speed 3.3V applications; it can be interfaced to 5V
signal environment for inputs.
A signal on the D INPUT is transferred to the Q
OUTPUT during the positive going transition of the
clock pulse.
CLR and PR are independent of the clock and
accomplished by a low setting on the appropriate
input.
It has same speed performance at 3.3V than 5V
AC/ACT family, combined with a lower power
consumption.
