Features  
Description  
• Hysteresis on Clock Inputs for Improved Noise The ’HC74 and ’HCT74 utilize silicon gate CMOS technology  
Immunity and Increased Input Rise and Fall Times  
• Asynchronous Set and Reset  
• Complementary Outputs  
to achieve operating speeds equivalent to LSTTL parts.  
They exhibit the low power consumption of standard CMOS  
integrated circuits, together with the ability to drive 10 LSTTL  
loads.  
[ /Title

CD74H  
C74,  
This flip-flop has independent DATA, SET, RESET and  
CLOCK inputs and Q and Q outputs. The logic level present  
at the data input is transferred to the output during the  
positive-going transition of the clock pulse. SET and RESET  
are independent of the clock and are accomplished by a low  
level at the appropriate input.
