TECHNICAL DATA
Dual JK Flip-Flop
IW4027B
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
