UNISONIC TECHNOLOGIES CO., LTD U74HCT73 CMOS IC DUAL J-K FLIP-FLOPS WITH CLEAR AND PRESET DESCRIPTION The U74HCT73 is a dual J-K negative-edge-triggered flip-flop. The clear ( CLR ) input can reset the output at a low level, regardless of the level of others inputs. when the CLR is inactive(high), data at the data inputs meeting the set-up time requirements are transferred to the outputs on the negative-going edge of the clock pulse. Following the hold-time interval, data J and k inputs can be changed without affecting the levels at the outputs. FEATURES * Wide supply voltage range from 4.5V to 5.5V * Low static power consumption; ICC=4μA (Max.)

Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
