(TOP VIEW)  
These octal positive-edge-triggered flip-flops  
utilize TTL circuitry to implement D-type flip-flop  
logic with a direct-clear (CLR) input.  
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. Clocktriggeringoccursataparticular  
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  
signal has no effect at the output.
