description/ordering information

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.

preventing damaging current backflow through the device when it is powered down.

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
