FEATURES:  
DESCRIPTION:  
• Common features:  
The FCT16543T/AT/CT/ET and FCT162543T/AT/CT/ET  
– 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)  
– Packages include 25 mil pitch SSOP, 19.6 mil pitch  
16-bit latched transceivers are built using advanced dual metal  
CMOS technology. These high-speed, low-power devices are  
organized as two independent 8-bit D-type latched transceiv-  
ers with separate input and output control to permit indepen-  
dent control of data flow in either direction. For example, the A-  
to-B Enable (xCEAB) must be LOW in order to enter data from  
the A port or to output data from the B port. xLEABcontrols the  
latch function. When xLEAB is LOW, the latches are transpar-  
TSSOP, 15.7 mil pitch TVSOP and 25 mil pitch Cerpack ent. A subsequent LOW-to-HIGH transition of xLEAB signal  
– Extended commercial range of -40°C to +85°C  
– VCC = 5V ±10%  
putstheAlatchesinthestoragemode. xOEABperformsoutput  
enable function on the B port. Data flow from the B port to the  
A port is similar but requires using xCEBA, xLEBA, and xOEBA  
inputs. Flow-through organization of signal pins simplifies  
layout. All inputs are designed with hysteresis for improved  
noise margin.  
The FCT16543T/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"liveinsertion"ofboardswhenusedasbackplanedrivers.  
The FCT162543T/AT/CT/ET have balanced output drive  
with current limiting resistors. This offers low ground bounce,  
minimal undershoot, and controlled output fall times–reducing  
the need for external series terminating resistors. The  
FCT162543T/AT/CT/ET are plug-in replacements for the  
FCT16543T/AT/CT/ET and 54/74ABT16543 for on-board bus  
interface applications.  
• Features for FCT16543T/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 FCT162543T/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
