HC5517 3 REN Ringing SLIC

HC5517 Data Sheet July 1998 File Number 4147.2 3 REN Ringing SLIC For ISDN Modem/TA and WLL he HC5517 is a ringing SLIC designed to accommodate a wide variety of local loop applications. The various applications include, basic POTS lines with answering machines and fax capabilities, ISDN networks, wireless local loop, and hybrid fiber coax (HFC) terminals. .

Features

of the HC5517 are complex impedance matching, pulse metering and transhybrid balance. The HC5517 is designed for use in systems where a separate ring generator is not economically feasible. The device is manufactured in a high voltage Dielectric Isolation (DI) process with an operating voltage range from -16V, for offhook operation and -80V for ring signal injection. The DI process provides substrate latch up immunity, resulting in a robust system design. Together with a secondary protection diode bridge and “feed” resistors, the device will withstand 1000V lightning induced surges, in a plast.
