8-Bit Buffers/Line Drivers  
Features  
Functional Description  
Function, pinout, and drive compatible with FCT and  
The FCT540T inverting buffer/line driver and the FCT541T  
non-inverting buffer/line driver are designed to be employed as  
memory address drivers, clock drivers, and bus-oriented  
transmitters/receivers. The devices provide speed and drive  
capabilities equivalent to 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 external components.  
F logic  
FCT-C speed at 4.1 ns max. (Com’l)  
FCT-A speed at 4.8 ns max. (Com’l)  
Reduced VOH (typically = 3.3V) versions of equivalent  
FCT functions  
Edge-rate control circuitry for significantly improved  
noise characteristics  
Power-off disable feature  
ESD > 2000V  
The outputs are designed with a power-off disable feature to  
allow for live insertion of boards.  
Matched rise and fall times  
Fully compatible with TTL input and output logic levels  
• Sink current  
Source current  
64 mA (Com’l), 48 mA (Mil)  
32 mA (Com’l), 12 mA (Mil)  
Extended commercial range of 40˚C to +85˚C
