Abstract
An inverter circuit arrangement that connects an IO-link master with a slave includes an AB class transistor circuit of which the currents are replicated by a current mirror to a terminal of the slave. A bias circuit provides bias voltages to the AB class transistors. A comparator forms a feedback between the master and slave terminals. The circuit provides for a bidirectional inversion to make a slave device IO-link compatible.
