ABSTRACT:
An address buffer circuit for comverting an address signal (A.sub.i) of a TTL level into an address signal (A) of a MOS level an its inverted signal (A) comprising: a pre-amplifier (P-AMP) for receiving the address signal having a TTL level; a main amplifier (M-AMP) comprising a flip-flop (FF.sub.3), a circuit for defining the operation of the flip-flop (FF.sub.3); and an output circuit (OUT) comprised of another flip-flop (FF.sub.4) for producing the address signals of a MOS level. In the pre-amplifier, a depletion type transistor (Q.sub.34) is used as a reference constant current source, which is independent of a power supply voltage (V.sub.DD), for the two values of the address signal of a TTL level.
