FEATURES:

DESCRIPTION:

DRIVE FEATURES:

APPLICATIONS:

The LVC244A device is organized as two 4-bit line drivers with separate

output-enable (OE) inputs. When

is low, the device passes data from

the A inputs to the Y outputs. When

is high, the outputs are in the high-

impedance state.

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

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

speed performance.

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

should be tied to V

through a pullup resistor; the minimum value of

the resistor is determined by the current-sinking capability of the driver.

Inputs can be driven from either 3.3V or 5V devices. This feature allows

the use of this device as a translator in a mixed 3.3V/5V system environment.

• High Output Drivers: ±24mA

• Reduced system switching noise

• 5V and 3.3V mixed voltage systems

• Data communication and telecommunication systems
