BL1062A Low Voltage Transmission Circuits

The BL1062 and BL1062A are Bipolar integrated circuits that perform all speech and line interface functions required in fully electronic telephone sets. They perform electronic switching between dialing and speech. The ICs operate at line voltage down to 1.6V DC to facilitate the use of more telepho.

BL1062A Features
