The HD74ALVC2G241 has dual bus buffer noninverted with 3-state output in a 8 pin package. Two noninverters are included in one circuit. Each circuit can be independently controlled by the enable signal OE or OE, which enables outputs when receiving a low or high level signal, respectively. To ensure the high impedance state during power up or power down, OE should be connected to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current sinking capability of the driver. Low voltage and high speed operation is suitable for the battery powered products (e.g., notebook computers), and the low power consumption extends the battery life.
