NTE7476
Integrated Circuit
TTL Dual JK FlipFlop with Preset and Clear
Description:
The NTE7476 is a dual JK flipflop in a 16Lead plastic DIP type package that contains two independent
JK positiveedgetriggered flipflops with individual JK clock, preset, and clear inputs. JK input is
loaded into the master while the clock is high and transferred to the slave on the hightolow transition.
J and K inputs must be stable while the clock is high.
