It is ideal for low powerand high speed 3.3V applications; it can beinterfaced to 5V signal environment for both inputsand outputs.Any nG output control governs four BUS BUFF-ERS. Output Enable input (nG) tied together givesfull 16-bit operation.When nG is LOW, the outputs are on. When nG isHIGH, the output are in high impedance state.Active bus-hold circuitry is provided to hold un-used or floating data inputs at a valid logic level.This device is designed to be used with 3 statememory address drivers, etc.The device circuits is including 26 series resis-tance in the outputs. These resistors permit to re-duce line noise in high speed applications.All inputs and outputs are equipped with protec-tion circuits against static discharge, giving them2KV ESD immunity and transient excess voltage.
