Product Summary

The SI3050-KT integrated direct access arrangement (DAA) provides a programmable line interface to meet global telephone line requirements. Available in one 20-pin and one 16-pin TSSOP, it eliminates the need for an analog front end (AFE), an isolation transformer, relays, opto-isolators, and a 2- to 4-wire hybrid.

Parametrics

Absolute maximum ratings: (1)DC Supply Voltage: –0.5 to 3.6 V; (2)Input Current, Si3050 Digital Input Pins: ±10 mA; (3)Digital Input Voltage: –0.3 to (VD + 0.3) V; (4)Ambient Operating Temperature Range: –40 to 100 ℃; (5)Storage Temperature Range: –65 to 150 ℃.

Features
