It is ideal for low power and very high speed 1.8 to 3.6V applications; it can be interfaced to 3.6V signal environment for both inputs and outputs. Any nG output control governs four BUS BUFFERS. Output Enable input (nG) tied together gives full 16-bit operation. When nG is LOW, the outputs are on. When nG is HIGH, the output are in high impedance state. This device is designed to be used with 3 state memory address drivers, etc. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
