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.

•

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

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
