SCCS036 - September 1994 - Revised March 2000  
8-Bit Buffers/Line Drivers  
Features  
Functional Description  
• Function and pinout compatible with FCT and F logic  
• 25Ω output series resistors to reduce transmission line  
reflection noise  
• FCT-C speed at 4.1 ns max. (Com’l) FCT-A speed at 4.8  
ns max. (Com’l)  
• TTL output level versions of equivalent FCT functions  
• Edge-rate control circuitry for significantly improved  
noise characteristics  
• Power-off disable feature permits live insertion  
• ESD > 2000V  
• Fully compatible with TTL input and output logic levels  
The FCT2240T and FCT2244T are octal buffers and line  
drivers that include on-chip 25Ω terminating resistors at each  
of the outputs, to minimize noise resulting from reflections or  
standing waves in high-performance applications. The on-chip  
resistors reduce overall board space and component count.  
Designed to be employed as memory address drivers, clock  
drivers, and bus-oriented transmitters/receivers, these devic-  
es provide speed and drive capabilities commensurate with  
their fastest bipolar logic counterparts while reducing power  
dissipation. The input and output voltage levels allow direct  
interface with TTL, NMOS, and CMOS devices without the  
need for external components.  
• Sink current 12 mA  
Source current15 mA  
The outputs are designed with a power-off disable feature to  
allow for live insertion of boards.  
• Extended commercial temp. range of –40˚C to +85˚C  
• Three-state outputs
