Concept for interfacing a first circuit requiring a first supply voltage and a second supply circuit requiring a second supply voltage |
摘要 |
An apparatus interfaces a first circuit using a first supply voltage and a second circuit using a second supply voltage different from the first supply voltage. The apparatus includes a driver circuit having a driver network comprising driver supply voltage terminals connected to controllable switches. The controllable switches include resistive elements or are separated from resistive elements. A receiver circuit has a receiving network comprising a resistive element and receiver supply voltage terminals and a connection line connecting the driver circuit and the receiving circuit. The controllable switches have two switch configurations, a first switch configuration resulting in a high voltage on the connection line and a second switch configuration resulting in a low voltage on the connection line.
