3.3V CMOS 16-BIT
BUFFER/DRIVER
IDT74LVC162244A
WITH 3-STATE OUTPUTS
AND 5 VOLT TOLERANT I/O
DESCRIPTION:
FEATURES:
TheLVC162244A16-bitbuffer/driveris builtusingadvanceddualmetal
CMOStechnology. The LVC162244Ais designedspecificallytoimprove
boththeperformanceanddensityof3-statememoryaddressdrivers,clock
drivers, andbus-orientedreceivers andtransmitters. The device canbe
usedasfour4-bitbuffers,two8-bitbuffers,orone16-bitbuffer. Thisdevice
provides true outputs and symmetrical active-low output-enable (OE)
inputs.
• 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
• CMOS power levels (0.4μ W typ. static)
• All inputs, outputs, and I/O are 5V tolerant
• Available in SSOP, TSSOP, and TVSOP packages
All pins of this 16-bit buffer/driver can be driven from either 3.3V or 5V
devices. Thisfeatureallowstheuseofthedeviceasatranslatorinamixed
3.3V/5Vsupplysystem.
The LVC162244A has series resistors in the device output structure
whichwillsignificantlyreduce line noise whenusedwithlightloads. This
driver has been developed to drive ±12mA at the designated threshold
levels.
DRIVE FEATURES:
• Balanced Output Drivers: ±12mA
• Low switching noise
APPLICATIONS:
• 5V and 3.3V mixed voltage systems
• Data communication and telecommunication systems
