Abstract
Various embodiments for improved I/O pin pull-up circuitry are disclosed. The pull-up devices according to the present invention minimize dissipation of crowbar current when the I/O pin is tri-stated. Circuit techniques are disclosed for minimizing the crowbar current as well as making the circuit high voltage tolerant.
