FAST CMOS 20-BIT  
BUFFERS  
Integrated Device Technology, Inc.  
FEATURES:  
• Common features:  
– 0.5 MICRON CMOS Technology  
– High-speed, low-power CMOS replacement for  
ABT functions  
DESCRIPTION:  
The FCT16827AT/BT/CT/ET and FCT162827AT/BT/CT/  
ET 20-bit buffers are built using advanced dual metal CMOS  
technology. These 20-bit bus drivers provide high-perfor-  
mance bus interface buffering for wide data/address paths or  
busses carrying parity. Two pair of NAND-ed output enable  
controls offer maximum control flexibility and are organized to  
operate the device as two 10-bit buffers or one 20-bit buffer.  
Flow-through organization of signal pins simplifies layout. All  
inputs are designed with hysteresis for improved noise mar-  
gin.  
The FCT16827AT/BT/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 FCT162827AT/BT/CT/ET have balanced output drive  
with current limiting resistors. This offers low ground bounce,  
minimalundershoot,andcontrolledoutputfalltimes–reducing  
the need for external series terminating resistors. The  
FCT162827AT/BT/CT/ET are plug-in replacements for the  
FCT16827AT/BT/CT/ET and ABT16827 for on-board inter-  
face 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 FCT16827AT/BT/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 FCT162827AT/BT/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
