The SN74LVC1G240DCKR is a single inverting Buffer/Driver designed for 1.65 to 5.5V VCC operation. It is a single line driver with a 3-state output. The output is disabled when the output-enable (OE) input is high. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor and 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.
Provides down translation to VCC
IOFF Supports live insertion, partial-power-down mode and back drive protection
Latch-up performance exceeds 100mA per JESD 78, class II
