It is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for inputs. It has same speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
