It is ideal for low power and low noise 3.3V applications. The device requires the same 3-STATE control input G to be set high to place the output in to the high impedance state. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
