DESCRIPTION/ORDERING INFORMATION

This dual buffer/driver is operational at 0.8-V to 2.7-V VCC, but is designed specifically for 1.65-V to 1.95-V VCC

operation.

The SN74AUC2G240 is designed specifically to improve the performance and density of 3-state memory

address drivers, clock drivers, and bus-oriented receivers and transmitters.

This device is organized as two 1-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low,

the device passes data from the A input to the Y output. When OE is high, the outputs are in the

high-impedance state.

NanoFree? package technology is a major breakthrough in IC packaging concepts, using the die as the

package.

To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup

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