These devices contain two independent J-K\ positive-edge-triggered flip-flops. A low level at the preset () or clear (
) inputs sets or resets the outputs regardless of the levels of the other inputs. When
and
are inactive (high), data at the J and K\ inputs meeting the setup-time requirements are transferred to the outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of the clock pulse. Following the hold-time interval, data at the J and K\ inputs can be changed without affecting the levels at the outputs. These versatile flip-flops can perform as toggle flip-flops by grounding K\ and tying J high. They also can perform as D-type flip-flops if J and K\ are tied together.
The SN54ALS109A and SN54AS109A are characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS109A and SN74AS109A are characterized for operation from 0°C to 70°C.
