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.
