Thesedevicesarepositive-edge-triggeredD-type  
flip-flops with a common enable input. The  
’HCT273 are similar to the ’HCT377, but feature  
a common clear enable (CLR) input instead of a  
latched clock.

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 positive-going pulse. When CLK is at either  
the high or low level, the D input has no effect at  
the output. The circuits are designed to prevent  
false clocking by transitions at CLR.

The SN54HCT273 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74HCT273 is characterized for operation from –40°C to 85°C.
