Input (INx) Default Low (Device With F Suffix Device) Schematics ENx VCCI VCCI VCCI ≅1M ≅1k Figure 8-5. Enable (ENx) Schematics VCCO ≅33 OUTx Figure 8-6. Output (OUTx) Schematics 8.6 Overvoltage Tolerant Input The input pins of this device, INx and ENx, support input signal voltage in excess of the supply voltage (VCCI) on the input side of the device as long as the voltage on the inputs remains below the voltages listed in the Section 6.3 , and Absolute Maximum Ratings . This allows the device to support input signal voltages on the inputs when the input supply, VCCI, is unpowered. In this use case, the outputs transition to the default output state when the input side no longer has a valid supply. These inputs also provide the capability of the inputs to down translate input signal voltages up to the VIMAX in the Section 6.3 . For example, an input signal 5V high-level can be used while VCCI is operating a 3.3V.
