7.4.1 Off-State Operation

The TPUL2T323 includes partial-power-down (Ioff) protection, which forces the outputs into a high-impedance state when the supply voltage is approximately 0V. In the powered-off state, voltages can be applied to the digital inputs and outputs and the device will not respond or have any back-powering. This protection does not apply to the RC pin.
