Abstract

One or more systems and techniques for communicating a signal between a first chip and a second chip using one or more circuits are provided. If the signal corresponds to a first voltage, one or more voltages are provided to one or more locations and a capacitive load is charged using a pull-up driver that is connected to a power supply. If the signal corresponds to a second voltage, one or more voltages are provided to one or more locations and the capacitive load is discharged using a pull-down driver that is connected to ground. When the first chip is powered off, a fail-safe mode is provided by configuring a cross control circuit to generate a bias to control one or more transistors.
