CY54/74FCT240T  
CY54/74FCT244T  
SCCS017 - May 1994 - Revised February 2000  
8-Bit Buffers/Line Drivers  
• Sink current  
Source current  
64 mA (Com’l), 48 mA (Mil)  
32 mA (Com’l), 12 mA (Mil)  
Features  
Function, pinout, and drive compatible with FCT and  
F logic  
Functional Description  
FCT-D speed at 3.6 ns max. (Com’l FCT244 only),  
FCT-C speed at 4.1 ns max. (Com’l),  
The FCT240T and FCT244T are octal buffers and line drivers  
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 consumption. The  
input and output voltage levels allow direct interface with TTL,  
NMOS, and CMOS devices without external components.  
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  
Matched rise and fall times  
The outputs are designed with a power-off disable feature to  
allow for live insertion of boards.  
Fully compatible with TTL input and output logic levels  
Extended commercial range of 40˚C to +85˚C
