OCTAL BUFFERS/DRIVERS

WITH 3-STATE OUTPUTS

DESCRIPTION

The U74AC240 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 inverted data from the A

inputs to the Y outputs.

The U74AC240 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

* ±24mA Output Driver at 5.5V
