AND 5 VOLT TOLERANT I/O
DESCRIPTION:
FEATURES:
TheLVC16823A18-bit registerisbuiltusingadvanceddualmetalCMOS
technology.This high-speed,low-powerregisteris idealforuseas abuffer
registerfordatasynchronizationandstorage.TheOutputEnable(OE)and
clock (CLK) controls are organized to operate each device as two 9-bit
registers orone 18-bitregisterwithcommonclock.Flow-throughorgani-
zationofsignalpinssimplifieslayout. Allinputsaredesignedwithhysteresis
forimprovednoise margin.
• 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
• Supports hot insertion
Allpins oftheLVC16823Acanbedrivenfromeither3.3Vor5Vdevices.
This feature allows the use of this device as a translator in a mixed 3.3V/
5Vsupplysystem.
• Available in SSOP, TSSOP, and TVSOP packages
The LVC16823A has been designed with a ±24mA output driver. The
driver is capable of driving a moderate to heavy load while maintaining
speedperformance.
DRIVE FEATURES:
• High Output Drivers: ±24mA
• Reduced system switching noise
APPLICATIONS:
• 5V and 3.3V mixed voltage systems
• Data communication and telecommunication systems
