ultra-low power and low noise applications, typically notebook and docking station. Any nG SWITCHES. Output Enable inputs (nG

output control governs two 10-bit BUS

)tied together gives full 20-bit operations. When nG LOW, the switches are on. When nG

is HIGH, the switches are in high impedance state. It has ultra high-speed performanc e at 5V near zero delay with low ON resistance. All inputs and outputs are equipped with protection circuits against st ati c discharge, giving them 2KV ESD immunity and transient excess vo ltage.
