CC  
The SN74LVT125 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 I . The I 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 V  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
