Input
Pullup
Synchronizing clock enable. When LOW, Q outputs will go LOW and nQ outputs will
go HIGH on the next LOW transition at IN inputs. Input threshold is VCC/2V. Includes a
37k
pullup resistor. Default state is HIGH when left floating. The internal latch is
clocked on the falling edge of the input signal IN1, IN2.
LVTTL/LVCMOS interface levels.
