| Zusammenfassung: | A pad driver 53 in an integrated circuit comprises a logic level converter 52 which is stated to be capable of converting a logic signal 40 from the core of the IC to a voltage level suitable for the pad circuit irrespective of whether the pad supply voltage 51 is higher or lower than the core supply voltage 54. The logic level converter receives a voltage supply 56 from a switch 55 which selects the higher of the pad or core voltages. The logic level converter may comprise a potential divider. |
