Title: Output driving circuit and transistor output circuit

Abstract: Disclosed herein are an output driving circuit and a transistor output circuit. The output driving circuit includes: a reference voltage generating unit generating a reference voltage; a level shift unit including a transistor latch and turning off a first transistor of a driving circuit or driving the first transistor; a driving circuit unit including the first transistor that is driven to apply power to a gate of an output transistor and a second transistor that is driven complementarily to the first transistor to lower a gate voltage of the output transistor and drive the output transistor; and an withstand voltage protecting unit that is driven by receiving a reference voltage and includes a first withstand voltage protecting unit for protecting transistors of the transistor latch and the first transistor for stable operations thereof and a second withstand voltage protecting unit for protecting the output transistor for a stable operation thereof.
