AM79C32A规格书详情
GENERAL DESCRIPTION
The Am79C30A Digital Subscriber Controller (DSC) Circuit and Am79C32A ISDN Data Controller (IDC) Circuit, shown in the Block Diagram, allow the realization of highly-integrated Terminal Equipment for the ISDN. The Am79C30A/32A is fully compatible with the CCITT-I-series recommendations for the S and T reference points, ensuring that the user of the device may design TEs which conform to the international standards.
