            Abstract : 
A fast and dense low-power multiple-valued I2L circuit that can be made in a standard Schottky process with double-layer metallisation is proposed. The circuit consists of pnp and npn current mirrors. Schottky diodes and a normally operated threshold npn transistor with a merged pnp transistor to clamp the npn transistor and prevent the npn from going too deeply into saturation. Propagation delay times below 1 ns can be obtained.
