ABSTRACT:
A biCMOS interface circuit receives a plurality of incoming signals at a first level and supplies a plurality of output signals at a second level. The interface circuit establishes control voltages which are used to maintain an identical trip point in each of a plurality of translator circuits. Generally, the trip point is set at midway between the "high" and the "low" levels of the incoming logic signal. The control voltages assure reliable performance over a wide operating environment.
