- 摘要：
- A voltage translator programmably converts signals generated from a first power-supply voltage to a second power-supply voltage, or vice-versa. In response to control signals, bootstrap switches connect either the first or second power supply to a first internal supply, and either the second or first power supply to a second internal supply. A pair of inverters are sourced by the first power supply and generate true and complement data signals. Cross-coupled p-channel load transistors are sourced by the second internal power supply. A differential pair of n-channel transistors have drains connected to the drains of the load transistors, and gates driven by the true and complement data signals. The bootstrap switches use boosted signals above the power-supply voltages to programmably connect full-voltage power supplies to the internal supplies.
