The SN74LVC2G04DCKR is a dual Inverter designed for 1.65 to 5.5V VCC operation. The device performs the Boolean function Y = A\\. 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.
The SN74LVC2G06DCKR is a dual inverter Buffer/Driver designed for 1.65 to 5.5V VCC operation. The output of this device is an open-drain which can be connected to other open-drain outputs to implement active-low, wired-OR or active-high wired-AND functions. The maximum sink current is 32mA. 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.
