decoder that supports the Bellcore TR-NWT-000030 and SR-TSV-002476 standards calling number identiļ¬cation (caller ID) and call waiting dual-tone signals. It has separate caller ID signal and call waiting signal inputs, which allows the gain for each input to be adjusted independently. It is fabricated in CMOS and features a power-down function, realizing low power dissipation operation.
