3.3V CMOS 12-BIT TO 24-BIT  
IDT74ALVCH162260  
MULTIPLEXED D-TYPE LATCH  
WITH 3-STATE OUTPUTS AND  
BUS-HOLD  
FEATURES:  
DESCRIPTION:  
• 0.5 MICRON CMOS Technology  
ThismultiplexedD-typelatchisbuiltusingadvanceddualmetalCMOS  
technology. The ALVCH162260 is used in applications in which two  
separate data paths mustbe multiplexedonto,ordemultiplexedfrom,a  
singledatapath.Typicalapplicationsincludemultiplexingand/ordemultiplexing  
addressanddatainformationinmicroprocessororbus-interfaceapplica-  
tions.This device alsois usefulinmemory-interleavingapplications.  
Three 12-bit I/O ports (A1A12, 1B1–1B12, and 2B1–2B12) are  
available for address and/or data transfer. The output-enable (OE1B,  
OE2B,andOEA)inputs controlthebus transceiverfunctions.The OE1B  
andOE2B controlsignals alsoallowbankcontrolinthe A-to-Bdirection.  
Address and/ordatainformationcanbestoredusingtheinternalstorage  
latches.The latch-enable (LE1B,LE2B,LEA1B,andLEA2B)inputs are  
usedtocontroldatastorage.Whenthelatch-enableinputishigh,thelatch  
is transparent.Whenthelatch-enableinputgoes low,thedatapresentat  
the inputs is latched and remains latched until the latch-enable input is  
returnedhigh.  
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 SSOP, TSSOP, and TVSOP packages  
DRIVE FEATURES:  
• Balanced Output Drivers: ±12mA (A port)  
High Output Drivers: ±24mA (B port)  
APPLICATIONS:  
The ALVCH162260has series resistors inthe device outputstructure  
oftheB”portwhichwillsignificantlyreducelinenoisewhenusedwithlight  
loads. This driverhas beendesignedtodrive ±12mAatthe designated  
threshold levels. The A” port has a ± 24mA driver.  
• 3.3V high speed systems  
• 3.3V and lower voltage computing systems  
The ALVCH162260has bus-hold”whichretains the inputs’laststate  
whenevertheinputgoestoahighimpedance.Thispreventsfloatinginputs  
andeliminates the needforpull-up/downresistors.
