Features  
Description  
• CD54/74FCT240, CD54/74FCT240AT - Inverting  
The CD54/74FCT240, 240AT, 241, 244 and 244AT three-  
state octal buffers/line drivers use  
a small-geometry  
• CD54/74FCT241, CD54/74FCT244, CD54/74FCT244AT -  
Non-Inverting  
BiCMOS technology. The output stage is a combination of  
bipolar and CMOS transistors that limits the output-HIGH  
level to two diode drops below VCC. This resultant lowering  
of output swing (0V to 3.7V) reduces power bus ringing (a  
source of EMI) and minimizes VCC bounce and ground  
bounce and their effects during simultaneous output  
switching. The output configuration also enhances switching  
speed and is capable of sinking 48mA to 64mA.  
• Buffered Inputs  
• Typical Propagation Delay:  
o
4.1ns at VCC = 5V, TA = 25 C (FCT240AT, FCT244AT)  
• SCR-Latchup-Resistant BiCMOS Process and Circuit  
Design  
The CD54/74FCT240, 240AT, 244 and 244AT have active-  
LOW output enables (1OE, 2OE). The CD54/74FCT241 and  
CD54/74FCT241AT have one active-LOW (1OE) and one  
active-HIGH (2OE) output enable.  
• FCTXXX Types - Speed of Bipolar FAST®/AS/S;  
FCTXXXAT Types - 30% Faster Than FAST/AS/S with  
Significantly Reduced Power Consumption  
• 48mA to 64mA Output Sink Current (Commer-  
cial/Extended Industrial)
