ABSTRACT:
An input signal provided to an input terminal is terminated by coupling the input terminal to a ground voltage through a pull down transistor if the input signal at the input terminal is at a “high” level and coupling the input terminal to a power voltage through a pull up transistor if the input signal at the input terminal is at a “low” level. Termination circuits are provided including on die termination circuits.
