U74AC74

DESCRIPTION 

The U74AC74 is a dual positive-edge-triggered D-type flip-flop.

The preset ( PRE ) and clear (CLR ) input can set or reset the 

output at a low level ,regardless of the level of others inputs .when 

the PRE and CLR are inactive(high), data at the data D input 

meeting the set-up time requirements is transferred to the outputs 

on the positive-going edge of the clock pulse. Following the 

hold-time interval, data D can be changed without affecting the 

levels at the outputs. 

FEATURES 

* Operating voltage rauge: VCC(OPR)=2V to 6V. 

* Inputs accept voltages to 6V 

* Max tpd at 10ns of 5V
