OCTAL BUFFERS AND LINE

DRIVERS WITH 3-STATE OUTPUTS

SOP-20



DESCRIPTION

The U74HC240 is a octal buffer and line driver 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.

SSOP-20

The U74HC240 is designed to improve the performance and

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

bus-oriented receivers and transmitters.

TSSOP-20

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

down, OE should be tied to V_CCthrough a pull-up resistor; and 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 t_pdof 9 ns from A to Y at 6V

* Low power consumption, I_CC= 8 μA (Max.) at 6V

* ±6 mA output driver at 5V

* Low Input Current of 1 μA Max
