A switching interface for routing RF signals. The interface comprises a buffer decoder which receives first, second and third control signals and then decodes the signals to selectively turn on five RF switches. The decoded output signals from the buffer decoder are supplied to five pair of switch drivers for the RF switches. When a logic one is provided to a switch driver, the switch driver sets the RF switch to an ON position. When a logic zero to a switch driver, the switch driver set the RF switch to an OFF position. A window comparator monitors the outputs of the switch drivers for each of the five RF switches. Whenever one of the two output signals from the switch drivers is within a preset voltage range the window comparator provides a logic one and a logic zero which are supplied to a bit decode circuit. The bit decode circuit then decodes the signals from each of the five window comparators, providing a three bit status signal which indicates that the switch drivers for each RF switch are operating normally. When, however, both output signals from any one of the five window comparators have the same state logic state, the bit decode circuit will provide at its output a three bit logic one error signal which indicates that one of the switch drivers is operating in an open circuit condition or a short circuit condition.
