Beschreibung von SN74AS109A
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.
