This device contains six buffers, four buffers are controlled by an enable input (G1) and the other two buffers are controlled by the other enable input (G2); the outputs of each buffer group are enabled when G1 and/or G2 inputs are held low, and when held high, these outputs are disabled in a high-impedance state. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
