(TOP VIEW)  
The ’ABT273 are 8-bit positive-edge-triggered  
D-type flip-flops with a direct clear (CLR) input.  
They are particularly suitable for implementing  
buffer and storage registers, shift registers, and  
pattern generators.

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  
pulse. Clock triggering occurs at a particular  
voltage level and is not directly related to the  
transition time of the positive-going pulse. When  
the clock (CLK) input is at either the high or low  
level, the D input signal has no effect at the output.

The SN54ABT273 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74ABT273 is characterized for operation from –40°C to 85°C.
