Automotive 3.3V, 1:1 (SPST), 4-channel FET bus switch

The SN74CBTLV3126-Q1 quadruple FET bus switch features independent line switches. Each switch is disabled when the associated output-enable (OE) input is low.

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 SN74CBTLV3126-Q1 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 pull down resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
