The MC145506P is a Dual Subscriber Line Interface Circuit (SLIC) manufactured by Motorola (MOTO).
Specifications:
- Function: Provides the necessary interface between a telephone line and digital switching systems.
- Configuration: Dual-channel SLIC for two independent subscriber lines.
- Operating Voltage: Typically ±5V to ±15V (dual supply).
- Package: 16-Pin DIP (Dual Inline Package).
- Technology: CMOS-based design for low power consumption.
- Applications: Telephone systems, PBX equipment, and telecommunications interfaces.
Descriptions:
- Integrates BORSHT (Battery feed, Overvoltage protection, Ringing, Supervision, Hybrid, and Test) functions.
- Supports loop current detection and ringing signal generation.
- Includes built-in overvoltage protection for enhanced reliability.
Features:
- Dual SLIC in a single package for space efficiency.
- Low power consumption due to CMOS technology.
- Compatible with standard telephony signaling.
- On-chip hybrid circuit for 2-wire to 4-wire conversion.
- Supports both ground-start and loop-start signaling modes.
This IC was commonly used in telecommunication infrastructure before newer integrated solutions became prevalent.
