SN74ALS114A

These SN54ALS114A and SN74ALS114A 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.

When Preset and Clear are 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 SN54ALS114A and SN74ALS114A  versatile flip-flops can perform as toggle flip-flops by tying J and K high.The SN54ALS114A is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74ALS114A is characterized for operation from 0°C to 70°C.
