Abstract
Disclosed embodiments provide backpower-safe test switches, devices, systems, and methods. By maintaining high impedance on an existing communications bus integrated circuit pin, disclosed embodiments prevent backpower of integrated circuits even when the integrated circuits are powered off. In a non-limiting aspect, disclosed embodiments facilitate increased final ASIC test coverage by facilitating multiplexing analog test bus on an existing ASIC pin.
