SN74ALS113A

These SN54ALS113A and SN74ALS113A  devices contain two independent J-K negative-edge-triggered flip-flops. A low level at the Preset input sets the outputs regardless of the
levels of the other inputs. When Preset PRE is inactive (high), data at the J and K inputs meeting the setup time requirements are transferred to the outputs on the negative-going edge of the clock pulse. 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 SN54ALS113A and SN74ALS113A   versatile flip-flops can perform as toggle flip-flops by tying J and K high. The SN54ALS113A is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74ALS113A is characterized for operation from 0°C to 70°C.
