SN74CBT3305C
DUAL FET BUS SWITCH
5-V BUS SWITCH WITH –2-V UNDERSHOOT PROTECTION
SCDS125B – SEPTEMBER 2003 – REVISED AUGUST 2005
This device is fully specified for partial-power-down application 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.
