description  
These monolithic positive-edge-triggered D-type  
flip-flops have a direct clear (CLR) input. The  
’HC175 feature complementary outputs from  
each flip-flop.

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 SN54HC175 is characterized for operation  
over the full military temperature range of –55°C  
to 125°C. The SN74HC175 is characterized for  
operation from –40°C to 85°C.
