INTEGRAL IW4027BN Datasheet
Dual JK Flip-Flop
High-Voltage Silicon-Gate CMOS
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 positivegoing 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.

This device c ontains p rote ction ci rcuitr y to guard a gainst damage d ue to high st atic voltages or electr ic
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, V

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
