DESCRIPTION. The UTC UM66TXXL series are CMOS LSI designed for using in door bell, telephone and toy application. It is an on-chip ROM programmed for. UM66T IC or melody integrated circuit pinout and datasheet. It is designed for use in bells, telephones, toys etc. It has an inbuilt tone and a beat generator. BT66T is an easy to use 3 terminal Melody generator IC. It is mainly used in circuits where a tone has to be played as a notification for the user.
