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

down, OE should be tied to VCC through a pull-up resistor; the

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

capability of the driver.

„ FEATURES

* Wide Supply Voltage Range from 2V to 6V

* Max tPD of 6.5 ns from A to Y at 5V

* Low Power Consumption, ICC = 4μA (Max.) at 5.5V

* ±24mA Output Driver at 5.5V
