TCM1506B Telephone Tone Ringer Drivers

The TCM1501B, TCM1506B, TCM1512B, TCM1531, TCM1532, TCM1536, and TCM1539 are monolithic integrated circuit telephone tone-ringer drivers that, when coupled with an appropriate transducer, replace the electromechanical bell. These devices are designed using BIDFET technology for use with either a Pie.
