Abstract
Integrated circuits such as programmable logic devices are provided with hotsocket detection circuitry. The hotsocket detection circuitry monitors signals on data pins and power supply voltages. If the data pins become active before the power supply voltages have reached appropriate levels, a hotsocket condition is identified. When a hotsocket condition is identified, driver circuitry on the integrated circuit can be disabled by a hotsocket signal. Conductive paths may be used to share hotsocket detectors among multiple blocks of input-output circuitry.
