FEATURES:  
DESCRIPTION:  
• Common features:  
– 0.5 MICRON CMOS Technology  
– High-speed, low-power CMOS replacement for  
ABT functions  
The FCT16240T/AT/CT/ET and FCT162240T/AT/CT/ET  
16-bit buffer/line drivers are built using advanced dual metal  
CMOS technology. These high-speed, low-power devices  
offerbus/backplaneinterfacecapabilitywithimprovedpacking  
density.Theflow-throughorganizationofsignalpinssimplifies  
layout. Thethree-statecontrolsaredesignedtooperatethese  
devices in a Quad-Nibble, Dual-Byte or single 16-bit word  
mode. All inputs are designed with hysteresis for improved  
noise margin.  
The FCT16240T/AT/CT/ET are ideally suited for driving  
high capacitance loads and low-impedance backplanes. The  
output buffers are designed with power off disable capability  
to allow "live insertion" of boards when used as backplane  
drivers.  
The FCT162240T/AT/CT/ET have balanced output drive  
with current limiting resistors. This offers low ground bounce,  
minimal undershoot, and controlled output fall times– reduc-  
ing the need for external series terminating resistors. The  
FCT162240T/AT/CT/ET are plug-in replacements for  
FCT16240T/AT/CT/ET and 54/74ABT16240 for on-board in-  
terface applications.  
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)  
– Packages include 25 mil pitch SSOP, 19.6 mil pitch  
TSSOP, 15.7 mil pitch TVSOP and 25 mil pitch Cerpack  
– Extended commercial range of -40°C to +85°C  
– VCC = 5V ±10%  
• Features for FCT16240T/AT/CT/ET:  
– High drive outputs (-32mA IOH, 64mA IOL)  
– Power off disable outputs permit “live insertion”  
– Typical VOLP (Output Ground Bounce) < 1.0V at  
VCC = 5V, TA = 25°C  
• Features for FCT162240T/AT/CT/ET:  
– Balanced Output Drivers: ±24mA (commercial),  
±16mA (military)  
– Reduced system switching noise  
– Typical VOLP (Output Ground Bounce) < 0.6V at  
VCC = 5V,TA = 25°C
