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 TTL output  
with additional drive capability at the high Logic level to per-  
mit the driving of bus lines without external pull-up resistors.  
When disabled, both the output transistors are turned off  
presenting a high-impedance 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 opposite logic levels, the disable time  
is shorter than the enable time of the outputs.
