Quad TRI-STATE Buffers  
É
General Description  
This device contains four independent gates each of which  
performs a non-inverting buffer function. The outputs have  
the TRI-STATE feature. When enabled, the outputs exhibit  
the low impedance characteristics of a standard LS output  
with additional drive capability to permit the driving of bus  
lines without external resistors. When disabled, both the  
output transistors are turned off presenting a high-imped-  
ance state to the bus line. Thus the output will act neither as  
a significant load nor as a driver. To minimize the possibility  
that two outputs will attempt to take a common bus to oppo-  
site logic levels, the disable time is shorter than the enable  
time of the outputs.
