Additional Details

The MC74HC76N consists of two independent J-K flip-flops with individual J, K, Clock, Direct Set (Preset), and Direct Clear inputs. Changes at the inputs will affect the flip-flop and output accordingly. This device is triggered on the negative transition of the clock pulse. The preset and clear are asynchronous inputs and override the clock and data inputs. The device is supplied in a 16-pin DIP package. Operating temperature ranges from -55°C to +125°C.
