Abstract
Integrated circuit device that uses tristate switching means to disconnect input/output pins from input buffers during a power down mode, thereby preventing current leakage through partially turned on MOS transistors inside input buffers. A transition detection means connected between the input/output pins and the controlling inputs of the tristate switching means monitors electronic signal at the input/output pins while the chip is in a power-down mode and turns on the tristate switching means when a signal transition is detected.
