Integrated Circuit
TTL − Dual J−K Flip−Flop with Preset and Clear
Description:
The NTE7476 is a dual J−K flip−flop in a 16−Lead plastic DIP type package that contains two independent
J−K positive−edge−triggered flip−flops with individual J−K clock, preset, and clear inputs. J−K input is
loaded into the master while the clock is high and transferred to the slave on the high−to−low transition.
J and K inputs must be stable while the clock is high.
