74109 Datasheet – Dual J-/K Flip-Flops, SN74109N – TI

Part Number: 74109

Function: Dual J-K Positive-Edge-Triggered Flip-Flops With Preset and Clear

Package: DIP 16 Pin

Manufacturer: Texas Instruments




The 74109 is 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.
