摘要：
An integrated circuit is adapted for dual use in three different ways: 1) it is powered by either of two different low or high voltage sources; 2) it may be connected to the IC package voltage reference pin in two different ways, using either an on-chip internal resistor or an in-package external resistor to limit the voltage/current to the IC; 3) the ESD structures are used not only for their well-known circuit protection function, but also as a conductive path for the high voltage operating source.
