Overview
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.
