AM79C32ATC

The AM79C32ATC is designed as one kind of digital subscriber controller circuit device that provides a 192-Kbit/s full duplex digital path over four wires between the TE located on the subscriber's premises and the NT or PABX linecard. And this device is fully compatible with the CCITT-I-series recommendations for the S and T reference points.

Features of the AM79C32ATC are:(1)Combines CCITT I.430 S/T-Interface Transceiver, D-Channel LAPD Processor, Audio; (2)Processor (DSC device only), and IOM-2 Interface in a single chip; (3)Special operating modes allow realization of CCITT I.430 power-compliant terminal equipment; (4)Certified protocol software support available; (5)CMOS technology, TTL compatible; (6)Flag generation/detection; (7)CRC generation / checking; (8)Zero insertion/deletion; (9)Four 2-byte address detectors; (10)32-byte receive and 16-byte transmit FIFOs.

The absolute maximum ratings of the AM79C32ATC can be summarized as:(1)Ambient temperature (TA): 0°C to +70°C;(2)Operating VCC range with respect to VSS: 4.75 V to 5.25 V;(3)DC output current, LS1, LS2 only: 100 mA;(4)DC input/output current (except LS1, LS2): 10 mA;(5)Voltage from any pin to VSS: VSS - 0.5 V to VCC + 0.5 V;(6)Maximum power dissipation: 1.5 W;(7)Lead temperature (soldering, 10 sec): 300°C;(8)Supply voltage to ground, potential continuous: 0 V to +7.0 V.
