TTP223 Capacitor Type Single Channel Touch Sensor Breadboard PC817 Photocoupler IC has aTTP223 capacitor touch sensor supports momentary or latching toggle modes. TTP223 works on the input voltage of 2V to 5. 5V DC. TTP223 capacitor type single channel touch sensor provides two working modes i. e., Fast mode and Low power mode which can be selected using the pad option (LPMB pin). Response time of capacitor type TTP223 Touch sensor is 60mS in fast mode whereas 220mS in low power mode. This sensor is designed to replace the traditional
