Abstract
A level shifting circuit for converting a lower logic level into a higher logic level is arranged to prevent a large through current from flowing when the level of an input signal varies. A latch circuit for latching an input binary signal comprises first and second transistors to which there are connected in series third and fourth transistors, respectively, for blocking a current during the level shifting period. Fifth and sixth transistors having a small current capacity are connected parallel to the set of first and third transistors and the set of second and fourth transistors, respectively, to quickly respond to a level change. The fifth and sixth transistors may be dispensed with.
