ABSTRACT:
An output driver for an integrated circuit. The output driver includes a core data terminal, a pad terminal, a pull-down transistor and a pull-up transistor. The pull-down and pull-up transistors are coupled to the pad terminal and have pull-down and pull-up control terminals, respectively. A first inverter circuit coupled between the core data terminal and the pull-down control terminal. First and second voltage level shifting differential amplifiers are coupled in series between the core data terminal and the pull-up control terminal.
