MSP430P315SIDLR

Description
The MT88E45B is a low power CMOS integrated circuit suitable for receiving the physical layer signals used in North American (Bellcore) Calling Identity Delivery on Call Waiting (CIDCW) and Calling Identity Delivery (CID) services. It is also suitable for ETSI and BT Calling LineIdentity Presentation (CLIP) and CLIP with Call Waiting services.
