3.3V CMOS OCTAL BUS  
TRANSCEIVER WITH 3-STATE  
IDT74LVCH2245A  
OUTPUTS, 5 VOLT TOLERANT I/O,  
AND BUS-HOLD  
FEATURES:  
DESCRIPTION:  
• 0.5 MICRON CMOS Technology  
This bus transceiveris builtusingadvanceddualmetalCMOStechnol-  
ogy. The LVCH2245Adevice is designedforasynchronous communica-  
tionbetweendata buses.The device transmits data fromthe Abus tothe  
B bus or from the B bus to the A bus, depending on the logic level at the  
direction-control(DIR)input.Theoutput-enable(OE)inputcanbeusedto  
disable the device sothe buses are effectivelyisolated.  
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using  
machine model (C = 200pF, R = 0)  
VCC = 3.3V ± 0.3V, Normal Range  
VCC = 2.7V to 3.6V, Extended Range  
• CMOS power levels (0.4μ W typ. static)  
• Rail-to-rail output swing for increased noise margin  
All inputs, outputs, and I/O are 5V tolerant  
• Supports hot insertion  
Inputs canbe drivenfromeither3.3Vor5Vdevices.This feature allows  
the use of this device as a translator in a mixed 3.3V/5V environment.  
The LVCH2245A has series resistors in the output structure of the B”  
port,whichwillsignificantlyreducelinenoisewhenusedwithlightloads. The  
driver has been designed to drive ±12mA at the designated threshold  
levels. The "A" port has a ±24mA driver.  
The LVCH2245A has bus-hold” which retains the inputs' last state  
whenevertheinputgoestoahigh-impedance.Thispreventsfloatinginputs  
andeliminates the needforpull-up/downresistors.  
Available in SOIC and QSOP packages  
DRIVE FEATURES:  
• Balanced Output Drivers: ±12mA (B Port)  
High Output Drivers: ±24mA (A Port)  
APPLICATIONS:  
• 5V and 3.3V mixed voltage systems  
Data communication and telecommunication systems
