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.

Features

• VCC = 2.0 V to 5.5 V operation

• All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)

• All outputs VO (Max.) = 5.5 V (@VCC = 0 V)

• Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)

• Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C)

• Output current ±8 mA (@VCC = 3.0 V to 3.6 V), ±16 mA (@VCC = 4.5 V to 5.5 V)
