Voltage protected level shifting off chip driver |
摘要 |
An output driver which maintains over voltage protection on individual circuit elements, providing either a level shifted logic high or a floating-state on its output. The output driver includes a latch driven by a set circuit and a reset circuit. The latch output drives an output stage which produces a level shifted logic high when the latch is set and a floating-state when the latch is reset. Minimal voltage is applied across individual circuit elements by supplying power in concurrent incremental voltage levels to the output driver.
