3.3V CMOS 32-BIT  
IDT74ALVCH32244  
BUFFER/ DRIVER WITH  
3-STATE OUTPUTS AND  
BUS-HOLD  
DESCRIPTION:  
FEATURES:  
This 32-bit buffer/driver is built using advanced dual metal CMOS  
technology. This high-speed, low power device offers bus/backplane  
interface capabilitywithimprovedpackingdensity.The device has a flow-  
throughorganizationforsimplifyingboardlayout.Thethree-statecontrols  
operatethisdeviceinaQuad-Nibble,Dual-Byteorsingle16-bitwordmode.  
Allinputs are designedwithhysteresis forimprovednoise margin.  
The ALVCH32244has beendesignedwitha ±24mAoutputdriver.This  
driver is capable of driving a moderate to heavy load while maintaining  
speedperformance.  
• 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  
• CMOS power levels (0.4μ W typ. static)  
• Rail-to-Rail output swing for increased noise margin  
Available in 96-ball LFBGA package  
The ALVCH32244 has bus-hold” which retains the inputs’ last state  
wheneverthe inputbus goes toa highimpedance. This prevents floating  
inputs andeliminates the needforpull-up/downresistors.  
DRIVE FEATURES:  
High Output Drivers: ±24mA  
• Suitable for Heavy Loads  
APPLICATIONS:  
• 3.3V high speed systems  
• 3.3V and lower voltage computing systems
