UNISONIC TECHNOLOGIES CO., LTD U74LVC2G240 CMOS IC DUAL BUFFER/DRIVER WITH 3-STATE OUTPUTS DESCRIPTION The U74LVC2G240 is a dual buffer or driver with 3-state outputs. It is designed for 1.65V to 5.5V operation. The U74LVC2G240 is composed 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. The 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.
