Abstract
This invention discloses a TTL compatible output buffer circuit which provides that in the state where the output signal thereof is high, no substantial current is provided inward of the buffer circuit from the output signal lead over a wide range of voltages applied to the output signal lead, including applied voltages substantially greater than that supplied by the voltage supply terminals of the circuit, with the circuit being further implemented in compound semiconductor technology.
