CMOS output voltage levels. If the device is enabled, 3 binary select inputs (A, All inputs and outputs are equipped with B, and C) determine which one of the outputs will protection circuits against static discharge, giving go low. If enable input G1 is held low or either G2A them 2KV ESD immunity and transient excess
