LOW-VOLTAGE QUADRUPLE
FET BUS SWITCH
CMOS IC
DESCRIPTION
The U74CBTLV3126 quadruple FET bus switch features
independent line switches. Each switch is disabled when the
associated output-enable (OE) input is low.
The 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-sinking
capability of the driver.
FEATURES
* 5-Ω Switch Connection Between Two Ports
* Standard ‘126-Type Pinout
* Ioff Supports Partial-Power-Down Mode Operation
