DUAL FET BUS SWITCH WITH LEVEL SHIFTING
5-V BUS SWITCH WITH –2-V UNDERSHOOT PROTECTION

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description/ordering information (continued)
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
power off.
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.
