This document is the datasheet of U74LVC2G240. U74LVC2G240 is a dual buffer or driver with 3-state outputs produced by UNISONIC TECHNOLOGIES CO., LTD. It is designed for 1.65V to 5.5V operation. U74LVC2G240 consists of two 1-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, data passes from A (input) to 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 pull-up resistor, and the minimum value of the resistor is determined by the current-sinking capability of the driver. U74LVC2G240 is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs and prevents damaging current backflow through the device when it is powered down.
