The SN74LVT125-Q1 features independent line drivers with 3-state outputs. Each output is in the high-impedance state when the associated output-enable (OE) input is high. Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. This current flows only when the output is in the high state and VO > VCC. The package thermal impedance is calculated in accordance with JESD 51-7.
