The HC5513 is a subscriber line interface circuit which is interchangeable with Ericsson's PBL3764 for distributed central office applications. Enhancements include immunity to circuit latch-up during hot plug and absence of false signaling in the presence of longitudinal currents.
The HC5513 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 (JI) ICs. The elimination of the leakage currents results in improved circuit performance for wide temperature extremes. The latch free benefit of the DI xxprocess guarantees operation under adverse transient conditions. This process feature makes the HC5513 ideally suited for use in harsh outdoor environments.
