<!--StartFragment-->The advancement of IoT technologies provides an increasing demand for high-performance organic logic circuits with low-power consumption. In this regard, organic antiambipolar transistors (AAT) are promising candidates. The transistor exhibits a negative differential transconductance (NDT). This feature of AATs has achieved multivalued logic circuits (MVLs) by a combination of n-type transistors. However, the operation voltages of MVLs were extremely high. In this study, we achieved 1.5 V operation of the ternary logic circuit using a zirconium dioxide (ZrO2) film as a high-dielectric gate insulator. The finding thus has the potential to fulfil the state-of-the art organic logic circuits.<!--EndFragment-->
