It is ideal for 4V to 5.5V VCC operations and ultra-low power and low noise applications, typically notebook and docking station. Any nG output control governs four 5-bit BUS SWITCHES. Output Enable inputs (nG) tied together gives full 20-bit operations. When nG is LOW, the switches are on. When nG is HIGH, the switches are in high impedance state. It has ultra high-speed performance at 5V near zero delay with low ON resistance. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
