The SM8222A/B is a calling number identiļ¬cation (caller ID) and call waiting signal (dual tone signal) receiver decoder IC that conforms with the TRNWT-000030 and SR-TSV-002476 (Bellcore) dialer telephone number display standards. It is implemented in CMOS and incorporates a power-down function for low power operation.
