3.3V CMOS OCTAL  
IDT74LVCH2244A  
BUFFER/DRIVER WITH 3-  
STATE OUTPUTS, 5 VOLT  
TOLERANT I/O, BUS-HOLD  
DESCRIPTION:  
FEATURES:  
Thisoctalbuffer/driverisbuiltusingadvanceddualmetalCMOStechnol-  
ogy. The LVCH2244A device is organized as two 4-bit line drivers with  
separateoutput-enable(OE)inputs.WhenOEislow,thedevicepassesdata  
from the A inputs to the Y outputs. When OE is high, the outputs are in the  
high-impedancestate.  
• 0.5 MICRON CMOS Technology  
• 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  
TheLVCH2244Ahasseriesresistorsinthedeviceoutputstructurewhich  
willsignificantlyreducelinenoisewhenusedwithlightloads.Thisdriverhas  
been designed to drive ±12mA at the designated threshold levels.  
Inputs can be driven from either 3.3V or 5V devices. This feature allows  
theuseofthisdeviceasatranslatorinamixed3.3V/5Vsystemenvironment.  
The LVCH2244A has “bus-hold” which retains the inputs’ last state  
whenevertheinputgoestoahighimpedance.This preventsfloatinginputs  
and eliminates the need for pull-up/down resistors.  
• Available in QSOP and TSSOP packages  
DRIVE FEATURES:  
• Balanced Output Drivers: ±12mA  
• Low switching noise  
APPLICATIONS:  
• 5V and 3.3V mixed voltage systems  
• Data communication and telecommunication systems
