This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. 8.2 Functional Block Diagram 8.3 Feature Description The open-drain configuration means that the device cannot provide its own output drive current; instead, it relies on pullup resistors to provide the "high" bus state. It can only drive the bus low. In the "Hi-Z" state, the SN74LVC2G07 acts as an open circuit and allows the external pullup to pull the bus high. Therefore, the pullup voltage determines the output level and therefore the SN74LVC2g07 can be used for up or down-translation. The device can sink 24 mA at 3 V while retaining an output voltage (VOL) of 0.55 V or lower. 8.4 Device Functional Modes Table 1 shows the device functional modes of the SN74LVC2G07 device. Table 1.
