| 摘要 |
A digital data signal voltage converter for converting a first digital data signal that is asserted at a first pair of voltage levels that are considered the inverse of one another, the two voltage levels being a first low voltage level and a first high voltage level, to a second digital data signal that is asserted at a second pair of voltage levels that are considered the inverse of one another, the second pair of voltage levels being a second low voltage level and a second high voltage level, the second high voltage level being higher than the first high voltage level. The voltage converter includes an active pull-up transistor and an active pull-down transistor, along with circuitry for controlling the second high voltage level. Three-state control may be provided to allow use as an input/output terminal.
