TR909 DLC/FLC SLIC with
Low Power Standby
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.
