PURPOSE:To obtain a semiconductor integrated circuit which operates at a relatively high speed with low current consumption and is integrated to a high degree by using TTL input and output buffers and an internal logical block in combination. CONSTITUTION:The TTL input buffer is formed of a bipolar transistor (TR), and the TT1 output buffer is formed of an MOSFET and a bipolar (TR). The internal logical block is formed of a CMOS gate array. The output signal from the CMOS gate is impressed directly to the gate of a phase splitter MOSFETM5 forming the TTL output buffer. The output of this FETM5 is transmitted to the totem pole type push-pull output circuit consisting of TRs Q1-Q4. Thus, the semiconductor integrated circuit device which operates at the relatively high speed with small current consumption and is integrated to the high degree is obtained.
