Abstract

A bi-directional level shifter is described that combines an input/output (I/O) signal and a direction control signal into a single signal, thereby reducing the number of total pins. The combination of I/O and direction is encoded by different voltage levels, and thus no information is encoded by currents. This advantageously keep power consumption low compared to conventional designs. Moreover, because a predetermined voltage encoding is used in which the bi-directional level shifter is configured to detect and respond via hardware, transitions between data flow are detected very quickly.
