FEATURES:  
• Common features:  
– Low input and output leakage 1µA (max.)  
– Extended commercial range of –40°C to +85°C  
– CMOS power levels  
– True TTL input and output compatibility  
– VOH = 3.3V (typ.)  
DESCRIPTION:  
TheIDToctalbuffer/linedriversarebuiltusinganadvanced  
dual metal CMOS technology. The FCT240T/FCT2240T and  
FCT244T/FCT2244Taredesignedtobeemployedasmemory  
and address drivers, clock drivers and bus-oriented transmit-  
ter/receivers which provide improved board density.  
The FCT540T and FCT541T/FCT2541T are similar in  
functiontotheFCT240T/FCT2240TandFCT244T/FCT2244T,  
respectively, except that the inputs and outputs are on oppo-  
site sides of the package. This pinout arrangement makes  
these devices especially useful as output ports for micropro-  
cessorsandasbackplanedrivers, allowingeaseoflayoutand  
greater board density.  
– VOL = 0.3V (typ.)  
– Meets or exceeds JEDEC standard 18 specifications  
– Product available in Radiation Tolerant and Radiation  
Enhanced versions  
– Military product compliant to MIL-STD-883, Class B  
and DESC listed (dual marked)  
TheFCT2240T, FCT2244TandFCT2541Thavebalanced  
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 resis-  
tors. FCT2xxxT parts are plug-in replacements for FCTxxxT  
parts.  
– Available in DIP, SOIC, SSOP, QSOP, TSSOP  
CERPACK and LCC packages  
• Features for FCT240T/FCT244T/FCT540T/FCT541T:  
– Std., A, C and D speed grades  
– High drive outputs (-15mA IOH, 64mA IOL)  
• Features for FCT2240T/FCT2244T/FCT2541T:  
– Std., A and C speed grades  
– Resistor outputs (-15mA IOH, 12mA IOL Com.)  
(-12mA IOH, 12mA IOL Mil.)  
– Reduced system switching noise
