The DLPC2607 device provides fail-safe I/O on all host interface signals (signals powered by VCC_INTF). This protection allows the device to drive these inputs high even when no I/O power is applied.
Under this condition, the DLPC2607 device does not load the input signal, nor draw excessive current that could degrade ASIC reliability. For example, the I2C bus from the host to other components would not be affected by powering off VCC_INTF to the DLPC2607 device. Note that TI recommends weak pullups or pulldowns on signals feeding back to the host to avoid floating inputs.
