Product Details

The 7476 IC or IC 7476 is a Dual, Separate Positive-Edge Triggered J-K Flip-Flop. With separate J-K inputs, as well as individual Clock, Preset and Clear Inputs. For the 7476 IC Flip-Flops, the input to the J-K pins is moved into the master when the clock signal is HIGH. The data is then transferred to the slave when the clock transitions from HIGH to LOW. The 7476 pin diagram or 7476 pinout is shown below.

Features
