Octal 3-STATE Buffer/Line Driver/Line Receiver  
General Description  
Features  
These buffers/line drivers are designed to improve both the  
performance and PC board density of 3-STATE buffers/  
drivers employed as memory-address drivers, clock driv-  
ers, and bus-oriented transmitters/receivers. Featuring 400  
mV of hysteresis at each low current PNP data line input,  
they provide improved noise rejection and high fanout out-  
puts, and can be used to drive terminated lines down to  
133.  
3-STATE outputs drive bus lines directly  
PNP inputs reduce DC loading on bus lines  
Hysteresis at data inputs improves noise margins  
Typical IOL (sink current)  
64 mA  
Typical IOH (source current) 15 mA  
Typical propagation delay times  
Inverting  
4.5 ns  
Noninverting 6 ns  
Typical enable/disable times 9 ns  
Typical power dissipation (enabled)  
Inverting  
450 mW  
Noninverting 538 mW
