Demultiplekser ehk demultipleksor on kommutaator ehk valikulülitus, millel on üks infosisend ja mitu väljundit. Juhtsisendite arv sõltub väljundite arvust ja vastupidi. Vastavalt juhtsignaalile kommuteeritakse infosisendi signaal ühte väljundisse. Väljundite arv on 2n, kus n on juhtsisendite arv. Järelikult saab kahe juhtsisendiga ehk kahebitise koodiga kommuteerida 4 väljundit, kolme juhtsisendiga 8 väljundit jne.
Strobeeritaval ehk keelusisendiga demultiplekseril on täiendav juhtsisend väljundsignaali väljalülitamiseks.
