DESCRIPTION:  
FEATURES:  
The IDT octal bidirectional transceivers are built using an  
advanced dual metal CMOS technology. The FCT245T/  
FCT2245T and FCT645T are designed for asynchronous  
two-way communication between data buses. The transmit/  
receive (T/R) input determines the direction of data flow  
through the bidirectional transceiver. Transmit (active HIGH)  
enablesdatafromAportstoBports,andreceive(activeLOW)  
from B ports to A ports. The output enable (OE) input, when  
HIGH, disables both A and B ports by placing them in HIGH  
Z condition.  
• 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.)  
– VOL = 0.3V (typ.)  
– Meets or exceeds JEDEC standard 18 specifications  
– Product available in Radiation Tolerant and Radiation  
Enhanced versions  
The FCT2245T has balanced drive outputs with current  
limiting resistors. This offers low ground bounce, minimal  
undershootandcontrolledoutputfalltimes-reducingtheneed  
for external series terminating resistors. The FCT2xxxT parts  
are plug-in replacements for FCTxxxT parts.  
– Military product compliant to MIL-STD-883, Class B  
and DESC listed (dual marked)  
– Available in DIP, SOIC, SSOP, QSOP, TSSOP  
CERPACK and LCC packages  
• Features for FCT245T/FCT645T:  
– Std., A, C and D speed grades  
– High drive outputs (-15mA IOH, 64mA IOL)  
• Features for FCT2245T:  
– Std., A and C speed grades  
– Resistor outputs (-15mA IOH, 12mA IOL Com.)  
(-12mA IOH, 12mA IOL Mil.)  
– Reduced system switching noise
