WITH 3-STATE OUTPUTS,

5 VOLT TOLERANT I/O

DESCRIPTION:

FEATURES:

TheLVC244Adeviceis organizedas two4-bitlinedrivers withseparate

output-enable (OE)inputs.WhenOE is low,the device passes data from

the Ainputs tothe Youtputs.WhenOEis high,the outputs are inthe high-

impedancestate.

• 0.5 MICRON CMOS Technology

• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using

machine model (C = 200pF, R = 0)

• VCC = 3.3V ± 0.3V, Normal Range

The LVC244A has been designed with a ±24mA output driver. This

driver is capable of driving a moderate to heavy load while maintaining

speedperformance.

To ensure the high-impedance state during power up or power down,

OE shouldbe tiedtoVCC througha pullupresistor;the minimumvalue of

the resistoris determinedbythe current-sinkingcapabilityofthe driver.

Inputs canbe drivenfromeither3.3Vor5Vdevices.This feature allows

theuseofthisdeviceasatranslatorinamixed3.3V/5Vsystemenvironment.

• VCC = 2.7V to 3.6V, Extended Range

• CMOS power levels (0.4μ W typ. static)

• Rail-to-rail output swing for increased noise margin

• All inputs, outputs, and I/O are 5V tolerant

• Supports hot insertion

• Available in SOIC, SSOP, QSOP, and TSSOP packages

DRIVE FEATURES:

• High Output Drivers: ±24mA

• Reduced system switching noise

APPLICATIONS:

• 5V and 3.3V mixed voltage systems

• Data communication and telecommunication systems
