8BIT FET BUS SWITCH
5V BUS SWITCH WITH 2V UNDERSHOOT PROTECTION
SCDS130A SEPTEMBER 2003 REVISED OCTOBER 2003
2
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 VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
