OCTAL BUFFERS/DRIVERS

WITH 3-STATE OUTPUTS

DESCRIPTION

The U74AC244 is a octal buffers/drivers with 3-state outputs. It is

organized as two 4-bit buffers/drivers with separate output-enable

( OE ) inputs. When OE is high, the Y outputs are in a

high-impedance state, and the outputs neither load nor drive the bus

lines. When OE is low, the device passes noninverted data from

the A inputs to the Y outputs.

The U74AC244 is designed to improve the performance and

density of 3-state memory address drivers, clock drivers, and

bus-oriented receivers and transmitters.

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

minimum value of the resistor is determined by the current-sinking

capability of the driver.

FEATURES

* Wide supply voltage range from 2V to 6V

* ±24 mA output driver at 5.5V
