Caller ID Service IC with Call Waiting
OVERVIEW
The SM8222A/B is a calling number identification
(caller ID) and call waiting signal (dual tone signal)
receiver decoder IC that conforms with the TR-
NWT-000030 and SR-TSV-002476 (Bellcore) dialer
telephone number display standards. It is imple-
mented in CMOS and incorporates a power-down
function for low power operation.
