description/ordering information
The SN74CBT3126 quadruple FET bus switch features independent line switches. Each switch is disabled
when the associated output-enable (OE) input is low.
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a
pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the
driver.
