The HD74LV125A features independent line drivers with three state outputs. Each output is disabled when the associated output enable (OE) input is high. To ensure the high impedance state during power up or power down, OE should be connected to VCC through a pull-down resistor; the minimum value of the resistor is determined by the current souring 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.
