description  
These circuits are positive-edge-triggered D-type  
flip-flops with a direct clear (CLR) input.  
9 10 11 12 13  
Information at the data (D) inputs meeting the  
setup time requirements is transferred to the  
Q 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 pulse.  
When CLK is at either the high or low level, the  
D input has no effect at the output.  
The SN54AHC273 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74AHC273 is characterized for operation from –40°C to 85 °C.
