Military 4-ch, 4.5-V to 5.5-V buffers with 3-state outputs

The ’BCT125A bus buffers feature independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE)\ input is high.

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.
