This bus buffer is designed specifically for low-voltage (3.3-V) VCC operation, but with the capability
to provide a TTL interface to a 5-V system environment.
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 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.
