TC74HC279AP/AF  
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic  
TC74HC279AP,TC74HC279AF  
Quad S-R Latch  
The TC74HC279A is a high speed CMOS QUAD S-R LATCH  
fabricated with silicon gate C2MOS technology.  
TC74HC279AP  
It achieves the high speed operation similar to equivalent  
LSTTL while maintaining the CMOS low power dissipation.  
Each latch has an independent Q output and Set and Reset  
inputs. S and R are active low. When S input is low, the Q  
output goes high and when R input is low, the Q output goes  
low. When both S and R are low, S takes precedence  
resulting Q = low. When both of S and R are held high, Q  
output doesn’t change.  
All inputs are equipped with protection circuits against static  
discharge or transient excess voltage.
