HC5549CMZ - Renesas Electronics
Description: The HC5549 Subscriber line interface circuit is a 100V dielectrically 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. A high and low voltage battery supply may be connected to the HC5549 so that power dissipation can be lowered in the off hook condition in these short loop
