One aspect of the invention is an integrated circuit (10,110) comprising a digital circuit operable to generate a first signal (21,111) and a driver circuit (20 and 30, 120 and 130) coupled to the signal generating circuit (21,111) and to an output load (40, 140). The driver circuit (20 and 30, 120 and 130) comprises a first transistor (MDA,MODA) operable to sink a first amount of current from an output node (38, 138) when activated and a second transistor (MDC,MODC) operable to sink a second am...

In an output circuit having an input/output terminal, first and second p-channel MOS transistors are serially connected between a power supply and the input/output terminal. An enable signal and an input signal are supplied to an NAND circuit. The gate of the second p-channel MOS transistor is controlled using the output signal of the NAND circuit, thereby outputting a signal through the input/output terminal. If a voltage of a signal received at the input/output terminal exceeds the power suppl...

Circuits and methods provide single-ended and differential signals. Single-ended drivers are used to, e.g., reduce pin capacitance. The output cell uses an inversion circuit, such as a phase splitter, to derive the differential signals from the same output signal and provide low skew between the differential signals at the output pins. Selection circuits are used to select between single-ended and differential output.

The present invention is related an output buffer that has one input pin and produces a two-bit output. The input levels are a ground voltage, a supply voltage, and a voltage that is halfway between ground and supply. The invention is related to producing a minimal current when the input voltage is halfway between the ground voltage and the supply voltage.
