SN74LVC2G240 - Dual Buffer/Driver With 3-State Outputs

This dual buffer driver is designed for 1.65-V to 5.5-V V_CC 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 V_CC 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 I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
