These devices contain two independent J-K negative-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. Whenandare inactive (high), data at the J and K inputs meeting the setup-time requirements is transferred to the outputs on the negative-going edge of the clock pulse (CLK). Clock triggering occurs at a voltage level and is not directly related to the fall time of the clock pulse. Following the hold-time interval, data at the J and K inputs may be changed without affecting the levels at the outputs. These versatile flip-flops can perform as toggle flip-flops by tying J and K high.
The SN54ALS112A is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS112ANSR is characterized for operation from 0°C to 70°C.
