It is ideal for low powerand high speed 3.3V applications; it can beinterfaced to 5V signal environment for both inputsand outputs.This IC is intended for two-way asynchronouscommunication between data buses; the directionof data transmission is determined by DIR input.The two enable inputs nG can be used to disablethe device so that the buses are effectively isolat-ed.Bus hold on data inputs is provided in order toeliminate the need for external pull-up or pull-down resistor.It has same speed performance at 3.3V than 5VAC/ACT family, combined with a lower power con-sumption.All inputs and outputs are equipped with protec-tion circuits against static discharge, giving them2KV ESD immunity and transient excess voltage.All floating bus terminals during High Z State mustbe held HIGH or LOW.
