IDT74FCT166244T/AT/CT  
FAST CMOS 16-BIT  
BUFFER/LINE DRIVER  
DESCRIPTION:  
FEATURES:  
The FCT166244T 16-Bit Buffer/Line Driver is for bus interface or signal  
bufferingapplicationsrequiringhighspeedandlowpowerdissipation. These  
deviceshaveaflowthroughpinorganization,andshrinkpackagingtosimplify  
board layout. All inputs are designed with hysteresis for improved noise  
margin. Thethree-statecontrolsallowindependent4-bit,8-bitorcombined16-  
bit operation. These parts are plug in replacements for ABT16244 where  
higher speed, lower noise or lower power dissipation levels are desired.  
The FCT166244T is suited for very low noise, point-to-point driving  
where there is a single receiver, or a very light lumped load (<100pF). The  
buffersaredesignedtolimittheoutputcurrenttolevelswhichwillavoidnoise  
and ringing on the signal lines without using external series terminating  
resistors.  
• 0.5 MICRON CMOS Technology  
• High-speed, low-power CMOS replacement for ABT functions  
• Typical tSK(o) (Output Skew) < 250ps  
• Low input and output leakage 1µA (max.)  
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using  
machine model (C = 200pF, R = 0)  
• Light drive balanced output of ±8mA  
• Minimal system switching noise  
• Typical VOLP (Output Ground Bounce) < 0.25V at VCC = 5V,  
TA = 25°C  
• Power off disable outputs permit “live insertion”  
• Available in SSOP and TSSOP packages
