Intersil HC5549
The HC5549 Subscriber line interface circuit is a 100V diellectrically isolated bipolar integrated circuit for use in short loop ISDN, PABX and Pairgain applications. The HC5549 has been optimized for low power as required for battery backed remote terminals or for applications requiring emergency powering from the line such as European ISDN NT1+ designs. The high battery supply can be used in the on-hook condition to allow interfacing to fax and answering machines that require 48V to detect end of call status.| Part No. | HC5549 |
