TCM1532 - Telephone Tone Ringer Drivers

Download the TCM1532 datasheet PDF. This datasheet also covers the TCM1501B variant, as both devices belong to the same telephone tone ringer drivers family and are provided as variant models within a single manufacturer datasheet.

General Description

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.
