3.3V CMOS 16-BIT  
IDT74ALVCH162244  
BUFFER/DRIVER WITH  
3-STATE OUTPUTS  
AND BUS-HOLD  
ꢀEATURES:  
• 0.5 MICRON CMOS Technology  
Typical tSK(o) (Output Skew) < 250ps  
• 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  
VCC = 2.5V ± 0.2V  
DESCRIPTION:  
This 16-bit buffer/driver is built using advanced dual metal CMOS  
technology. The ALVCH162244is designedspecificallytoimprove the  
performance and density of 3-state memory address drivers, clock  
drivers,andbus-orientedreceivers andtransmitters.The device canbe  
usedasfour4-bitbuffers,two8-bitbuffers,orone16-bitbuffer.Itprovides  
trueoutputs andsymmetricalactive-lowoutput-enable(OE)inputs.  
The ALVCH162244has series resistors inthe device outputstructure  
whichwillsignificantlyreduce line noise whenusedwithlightloads.This  
driver has been designed to drive ±12mA at the designated threshold  
levels.  
• CMOS power levels (0.4µ W typ. static)  
• Rail-to-Rail output swing for increased noise margin  
Available in SSOP, TSSOP, and TVSOP packages  
The ALVCH162244has bus-hold”whichretains the inputs’laststate  
whenevertheinputbus goes toahighimpedance.This prevents floating  
inputs andeliminates the needforpull-up/downresistors.  
DRIVE ꢀEATURES:  
• Balanced Output Drivers: ±12mA  
Low switching noise  
APPLICATIONS:  
• 3.3V high speed systems  
• 3.3V and lower voltage computing systems
