Hi,Tomovill

The um66t19s is a melody generator. um66txxy where xx = 08,11,20,32 and y = s or l are melody generator too. For more about melody generator go to https://www.electronic-circuits-diagrams.com/alarmsimages/alarmsckt7.shtml.
For equivalente ic (m66,m66t) and datasheet go to **broken link removed**
