3.3V CMOS OCTAL  
BIDIRECTIONAL  
TRANSCEIVERS  
Integrated Device Technology, Inc.  
FEATURES:  
DESCRIPTION:  
• 0.5 MICRON CMOS Technology  
The FCT3245/A octal transceivers are built using ad-  
vanced dual metal CMOS technology. These high-speed,  
low-power transceivers are ideal for synchronous communi-  
cation between two busses (A and B). The direction control  
pin(DIR)controlsthedirectionofdataflow. Theoutputenable  
pin (OE) overrides the direction control and disables both  
ports. All inputs are designed with hysteresis for improved  
noise margin.  
The FCT3245/A have series current limiting resistors.  
These offer low ground bounce, minimal undershoot, and  
controlled output fall times-reducing the need for external  
series terminating resistors.  
• ESD > 2000V per MIL-STD-883, Method 3015;  
> 200V using machine model (C = 200pF, R = 0)  
• 25 mil Center SSOP and QSOP Packages  
• Extended commercial range of -40°C to +85°C  
• VCC = 3.3V ±0.3V, Normal Range or  
VCC = 2.7V to 3.6V, Extended Range  
• CMOS power levels (0.4µW typ. static)  
• Rail-to-Rail output swing for increased noise margin  
• Military product compliant to MIL-STD-883, Class B
