Intersil HC5523
The HC5523 is a subscriber line interface circuit which is interchangeable with Ericsson’s PBL3764A/4 for distributed central office applications. The HC5523 is fabricated in a High Voltage Dielectrically Isolated (DI) Bipolar Process that eliminates leakage currents and device latch-up problems normally associated with junction isolated ICs. The elimination of the leakage currents results in improved circuit performance for wide temperature extremes.| Part No. | HC5523 |
