TECHNICAL DATA IW027B Dual JK Flip-Flop The IW027B is a Dual JK Flip-Flop which is edge-triggered and features independent Set, Reset, and Clock inputs. Data is accepted when the Clock is LOW and traferred to the output on the positive-going edge of the Clock. The active HIGH asynchronous Reset and Set are independent and override the J, K, or Clock inputs. The outputs are buffered for best system performance. Operating oltage Range: 3.0 to 1 Maximum input current of 1 μa at 1 over full package-temperature range; 0 na at 1 and 25 C Noise margin (over full package temperature range): 1. min @ supply 2. min @. supply 2.5 min @. supply ORDERING INFORMATION IW027BN Plastic IW027BD SOIC T A = -55 to 125 C for all packages LOGIC DIAGRAM PIN ASSIGNMENT FUNCTION TABLE Inputs Outputs PIN 16 = PIN = GND Set Reset Clock J K Q n+1 Q n+1 L H X X X L H H L X X X H L H H X X X H H L L L L No change L L H L H L L L L H L H L L H H Qn Qn X = don t care Qn+1 = State After Clock Positive Traition

However, precautio must be taken to avoid applicatio of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation IN should be cotrained to the range GND IN. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or ). Unused outputs must be left open.
