The SN74CBTLV3126 quadruple FET bus switch features independent line switches. Each switch is disabled when the
associated output-enable (OE) input is low.
This device is fully specified for partial-power-down applications using Ioff. The Ioff feature ensures that
damaging current will not backflow through the device when it is powered down. The device has isolation during
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-sinking capability of the driver.
