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 transceiver is built using advanced dual metal CMOS technol-  
ogy. The LVCH2245A device is designed for asynchronous communica-  
tion between data buses. The device transmits data from the A bus to the  
B bus or from the B bus to the A bus, depending on the logic level at the  
direction-control (DIR) input. The output-enable (OE) input can be used to  
disable the device so the buses are effectively isolated.  
• 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 can be driven from either 3.3V or 5V devices. 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  
and eliminates the need for pull-up/down resistors.  
• Available in SOIC, SSOP, QSOP, and TSSOP 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
