description/ordering information
The SN74CBT3125 quadruple FET bus switch features independent line switches. Each switch 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 V_CC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
