Description
The HD74LV126A features independent line drivers with three state outputs. Each output is disabled when the
associated output enable (OE) input is low. To ensure the high impedance state during power up or power down, OE
should be connected to GND 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.
