DESCRIPTION

The BT8028 is a CMOS LSI chip which electronically plays a prearranged melody. Selection of melody start signal is

possible by mask option: orders specification suffix "L" indicate Level Hold Mode, and suffix "S" indicate One Shot

Mode. The Universal version (as One Shot or Level Hold Mode) is possible also (suffix "U").
