BUFFER/DRIVER WITH 3-

STATE OUTPUTS

AND 5 VOLT TOLERANT I/O

FEATURES:

DESCRIPTION:

• 0.5 MICRON CMOS Technology

This octal buffer/driver is built using advanced dual metal CMOS

technology. The LVC2244Adevice is organizedas two4-bitline drivers

with separate output-enable (OE) inputs. When OE is low, the device

passesdatafromtheAinputstotheYoutputs. WhenOEishigh,theoutputs

are inthe high-impedance state.

• 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)

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

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

• Available in TSSOP package

Toensure the high-impedance state duringpoweruporpowerdown,

OE shouldbe tiedtoVccthrougha pullupresistor;the minimumvalue of

the resistoris determinedbythe current-sinkingcapabilityofthe driver.

DRIVE FEATURES:

• Balanced Output Drivers: ±12mA

• Low switching noise

APPLICATIONS:

• 5V and 3.3V mixed voltage systems

• Data communication and telecommunication systems
