US Patent 11791820 Output circuit, transmission circuit, and semiconductor integrated circuit
An output circuit includes: a first input transistor that is provided between a first power supply line and a first intermediate node; a second input transistor that is provided between a second intermediate node and a second power supply line; a first cascode transistor that is provided between the first intermediate node and an output node, and receives a first clip voltage from a first voltage generation circuit; a second cascode transistor that is provided between the output node and the second intermediate node, and receives a second clip voltage from a second voltage generation circuit; a first switch transistor that is provided between the first intermediate node and a gate of the first cascode transistor, and turns on during power down; and a second switch transistor that is provided between the second intermediate node and a gate of the second cascode transistor, and turns on during power down.
