The translators provide voltage level translation for 2.5V, 3.3V and 5V busses, ±4kV human body model ESD, 1V precharging and glitch filtering of the bus pins which, Linear claims, make the address translators suitable for live board insertion and removal applications. A pass-through mode can disable the address translation and allow general call addressing by the master. The translators are designed to recover automatically from abnormal bus conditions like bus stuck low or premature stop.
