74LS109 Dual J-K Positive Edge-Triggered Flip-Flop IC (74109 IC)

74LS109 Dual J-K Positive Edge-Triggered Flip-Flop IC DIP-16 Package

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 levels of the other inputs. The 74LS109 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. 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 grounding K and tying J high. Featured by Sharvi Electronics They also can perform as D-type flip-flops if J and K are tied together. The 74LS109 is characterized for operation from 0°C to 70°C.
