features independent Set, Reset, and Clock inputs. Data is accepted when the Clock is LOW and transferred to the output on the positive-going edge of the Clock. The active HIGH asynchronous Reset and Set are independent and override the J, K, or Clock inputs. The outputs are buffered for best system performance.
- Operating Voltage Range: 3.0 to 18 V
