Part Number : 74109
Function :Dual J-K Positive-Edge-Triggered Flip-Flops With Preset and Clear
Manufacturer : Texas Instruments
Pinout : 
Description
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 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 positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of the clock pulse.
