TECHNICAL DATA IW4027B Dual JK Flip-Flop The IW4027B 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 transferred 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 Voltage Range: 3.0 to 18 V • Maximum input current of 1 μA at 18 V over full package-temperature range; 100 nA at 18 V and 25°C • Noise margin (over full package temperature range): 1.0 V min @ 5.0 V supply 2.0 V min @ 10.0 V supply 2.5 V min @ 15.0 V supply ORDERING INFORMATION IW4027BN Plastic IW4027BD SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE Inputs Set Reset Clock PIN 16 =VCC PIN 8 = GND Outputs J K Qn+1 Qn+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 L L H L H L L L L H L H L L H H Qn Qn No change X = don’t care Qn+1 = State After Clock Positive Transition Rev. 00 IW4027B MAXIMUM RATINGS* Symbol Parameter VCC DC Supply Voltage (Referenced to GND) VIN DC Input Voltage (Referenced to GND) IIN DC Input Current, per Pin PD Power Dissipation in Still Air, Plastic DIP, SOIC Package Ptot Power Dissipation per Output Transistor Tstg Storage Temperature TL Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) Value Unit -0.5 to +20 V -0.5 to VCC +0.5 V ±10 mA 500** mW 100 mW -65 to +150 °C 260 °C * Maximum Ratings are those values beyond which damage to the device may occur.

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