METHOD AND APPARATUS TO ACTIVELY SINK CURRENT IN AN INTEGRATED CIRCUIT WITH A FLOATING I/O SUPPLY VOLTAGE |
摘要 |
Described is an apparatus and a method for pulling an integrated circuit I/O pad to a known state and providing a current path between the pad and a source of potential during periods when an I/O voltage is likely to be floating. At least one I/O transistor coupled between the I/O pad and a source of potential is provided. Also provided is a combinatorial circuit connected to the I/O transistor to turn on the I/O transistor during periods that the I/O voltage is likely to be floating. |
