CLK  
These monolithic, positive-edge-triggered flip-  
flops utilize TTL circuitry to implement D-type  
flip-flop logic with a direct clear input.  
GND  
Information at the 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 input is at  
either the high or low level, the D input signal has  
no effect ar the output.

These flip-flops are guaranteed to respond to  
clock frequencies ranging form 0 to 30 megahertz  
while maximum clock frequency is typically 40  
megahertz. Typical power dissipation is 39  
milliwatts per flip-flop for the 273 and 10 milliwatts  
for the LS273.
