Description  
The ’HC174 and ’HCT174 are edge triggered flip-flops which  
utilize silicon gate CMOS circuitry to implement D-type flip-  
flops. They possess low power and speeds comparable to low  
power Schottky TTL circuits. The devices contain six master-  
slave flip-flops with a common clock and common reset.  
Data on the D input having the specified setup and hold  
NOTE: When ordering, use the entire part number. The suffix 96  
denotes tape and reel. The suffix T denotes a small-quantity reel of  
250.
