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.
