ABSTRACT:
An interface output stage includes a pull-up circuit and a pull-down circuit connected to a positive power supply signal line having a first voltage, an output signal line having an output voltage and a negative power supply signal line having a second voltage. The pull-up circuit includes a single output transistor and a body snatcher circuit, both interconnected between the positive power supply signal line and the output signal line. The body snatcher circuit ties the bodies of the output transistor and the transistors forming the body snatcher circuit to either the first voltage or the output voltage. The pull-down circuit is designed generally similar to the pull-up circuit to tie bodies of its transistors to either the output voltage or the second voltage.
