Features  
Description  
• Buffered Inputs  
The CD54/74FCT245 octal bus transceiver uses a small  
geometry BiCMOS technology. The output stage is a combi-  
nation of bipolar and CMOS transistors that limits the output

ground bounce and their effects during simultaneous output  
switching. The output configuration also enhances switching  
speed and is capable of sinking 48mA to 64mA.  
• Speed of Bipolar FAST™/AS/S  
• 64mA Output Sink Current (74 Series)  
• 48mA Output Sink Current (54 Series)  
The CD54/74FCT245 is a noninverting, three-state, bidirec-  
tional transceiver/buffer intended for two-way transmission  
from”A” bus to “B” bus or “B” bus to “A” bus. The logic level  
present on the Direction Input (DIR) determines the data direc-  
tion. When the Output Enable input is HIGH, the outputs are in  
the high impedance state.
