description  
These monolithic positive-edge-triggered D-type  
flip-flops have a direct clear (CLR) input.  
NC – No internal connection  
Information at the data (D) inputs meeting the setup time requirements is transferred to the outputs on the  
positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not  
directly related to the transition time of the positive-going edge of CLK. When CLK is at either the high or low  
level, the D input has no effect at the output.  
The SN54AHCT174 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74AHCT174 is characterized for operation from –40°C to 85°C.
