Hex/Quad D Flip-Flops with Clear  
General Description  
Features  
Y

Y
Y

LS174 contains six flip-flops with single-rail outputs  
These positive-edge-triggered flip-flops utilize TTL circuitry  
to implement D-type flip-flop logic. All have a direct clear  
input, and the quad (175) versions feature complementary  
outputs from each flip-flop.  
LS175 contains four flip-flops with double-rail outputs  
Buffered clock and direct clear inputs  
Individual data input to each flip-flop  
Applications include:  
Buffer/storage registers  
Shift registers  
Pattern generators  
Information at the D inputs meeting the setup time require-  
ments is transferred to the Q outputs on the positive-going  
edge of the clock pulse. Clock triggering occurs at a particu-  
lar 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  
at the output.

Typical clock frequency 40 MHz  
Typical power dissipation per flip-flop 14 mW
