Mai keɓantaccen siginar fitarwa na shigarwar transistor yana canza siginar shigarwa daga lambar sadarwa ko kusanci zuwa fitarwa ta transistor ta hanyar keɓewa. Ana nuna aikin gano kuskuren layi ta hasken LED akan saman tsarin. Ana amfani da maɓalli na ƙirar don zaɓar lokaci na tashar kuma ko ana buƙatar aikin gano kuskuren layi.
Wannan samfurin yana buƙatar a samar da wutar lantarki da kansa, kuma an keɓance samar da wutar lantarki, shigarwa da tashoshi masu fitarwa.
