Description and Introduction

SLIC, Ringing, VoIP, 75/85/100V, Gnd Start, LB=53/58dB The HC55185 is a subscriber line interface circuit (SLIC) manufactured by ON Semiconductor. It is designed for central office (CO) and PBX applications, providing the necessary functions for interfacing with telephone lines. Key specifications include:

- **Operating Voltage**: Typically operates with a supply voltage range of -24V to -80V.
- **Current Limit**: Features programmable current limiting for short-circuit protection.
- **Power Dissipation**: Designed for low power dissipation.
- **Package**: Available in a 28-pin PLCC (Plastic Leaded Chip Carrier) package.
- **Functions**: Includes battery feed, overvoltage protection, ringing, and supervision capabilities.
- **Compliance**: Meets relevant telecommunications standards for CO applications.

For detailed electrical characteristics and application-specific parameters, refer to the official datasheet from ON Semiconductor.
