These devices contain two independent J-K\ positive-edge-triggeredflip-flops. A low level at the preset (1 or 2) or clear (1 or 2) input sets or resets the outputsregardless of the levels of the other inputs. When and are inactive (high), data at the Jand K\ inputs meeting the setup time requirements are transferred tothe outputs on the positive-going edge of the clock pulse. Clocktriggering occurs at a voltage level and is not directly related tothe rise time of the clock pulse. Following the hold-time interval,data at the J and K\ inputs may be changed without affecting thelevels at the outputs. These versatile flip-flops can perform astoggle flip-flops by grounding K\ and tying J high. They also canperform as D-type flip-flops if J and K\ are tied together.
The 54ACT11109 is characterized for operation over the fullmilitary temperature range of -55°C to 125°C. The74ACT11109 is characterized for operation from -40°C to85°C.
