DESCRIPTION

This dual buffer driver is designed for 1.65-V to 5.5-V

VCC operation.

The SN74LVC2G240 device is designed specifically

to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-

oriented receivers and transmitters.

NanoFree? package technology is a major

breakthrough in IC packaging concepts, using the die

as the package.

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.

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.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the

outputs, preventing damaging current backflow

through the device when it is powered down.
