ABSTRACT:
An arrangement for preventing damage to a circuit of an integrated circuit due to the occurrence of voltage transients introduced externally to the integrated circuit. Generally, the arrangement provides protection against voltage transients for certain circumstances and disables such protection for other circumstances. Transient protection is enabled when the power of the transient would cause breakdown of the transistors of the integrated circuit. Otherwise, transient protection is disabled.
