Octal Buffer/Line Driver with 25Series Resistors  
in the Outputs  
Features  
General Description  
Guaranteed latchup protection  
The ABT2244 is an octal buffer and line driver designed  
to drive the capacitive inputs of MOS memory drivers,  
address drivers, clock drivers, and bus-oriented trans-  
mitters/receivers.  
High-impedance, glitch-free bus loading during entire  
power up and power down cycle  
Nondestructive, hot-insertion capability  
The 25series resistors in the outputs reduce ringing  
and eliminate the need for external resistors.
