DESCRIPTION
This single buffer/driver is designed for 1.65-V to 5.5-
V VCC operation.
The SN74LVC1G240 is a single line driver with a 3-
state output. The output is disabled when the output- enable (OE) input is high.
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.
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.
