description/ordering information
The SN74CBTLV3125 quadruple FET bus switch features independent line switches. Each switch is disabled
when the associated output-enable (OE) input is high.
This device is fully specified for partial-power-down applications using I . The I feature ensures that
off
off
damaging current will not backflow through the device when it is powered down. The device has isolation during
power off.
To ensure the high-impedance state during power up or power down, OE should be tied to V
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
