Abstract
The present invention includes a circuit having an input section that is operated from an operating voltage which is lower than a supply voltage of the circuit. The operating voltage is established so that the operating voltage minus the voltage of a high level TTL signal is less than an upper level threshold voltage of the input section. The circuit couples the output of the input section to the supply voltage thereby increasing the voltage on the output of the input section to a voltage greater than the operating voltage. In addition, the circuit enables a current source during a portion of a low-to-high transition on an output of the circuit. The current source provides high current drive during the portion of the transition. Since the current source is only enabled during the portion of the transition, static power dissipation is minimized.
