N-ary input to n-1 binary outputs level shift circuit for I2L

摘要

A circuit for level adaptation between an I2L circuit and a preceding combinatory logic circuit. The input current for the I2L circuit is supplied by a direct current source which is connected to several switches which are controlled by the level on the output of the combinatory logic circuit, at least one of the outputs thereof being connected to an input of the I2L circuit via a current mirror.
