آی سی HC3-5509B-9 یک رابط یا اینترفیس کمکی خطوط تلفن از نوع DIP-28 می باشد. این آی سی در بردهای سوییچینگ مراکز تلفن بسیار کاربرد دارد
The HC-5509B telephone Subscriber Line Interface Circuit
integrates most of the BORSCHT functions on a monolithic
IC.
The device is manufactured in a Dielectric Isolation (DI)
process and is designed for use as a high voltage interface
between the traditional telephone subscriber pair (Tip and
Ring) and the low voltage filtering and coding/decoding functions
of the line card. Together with a secondary protection diode bridge and “feed” resistors, the device will withstand 1000V lightning induced surges, in plastic packages.
The SLIC also maintains specified transmission performance in the presence of
externally induced longitudinal currents.
The BORSCHT functions that the SLIC provides are:
• Battery Feed with Subscriber Loop Current Limiting
• Overvoltage Protection
• Ring Relay Driver
• Supervisory Signaling Functions
• Hybrid Functions (with External Op-Amp)
• Test (or Battery Reversal) Relay Driver
Features
• DI Monolithic High Voltage Process
• Compatible with Worldwide PBX and CO Performance Requirements
• Controlled Supply of Battery Feed Current with Programmable Current Limit
• Operates with 5V Positive Supply (V)
• Internal Ring Relay Driver and a Utility Relay Driver
• High Impedance Mode for Subscriber Loop
• High Temperature Alarm Output
• Low Power Consumption During Standby Functions
• Switch Hook, Ground Key, and Ring Trip Detection
• Selective Power Denial to Subscriber
• Voice Path Active During Power Denial
• On Chip Op-Amp for 2 Wire Impedance Matching
Applications
• Solid State Line Interface Circuit for PBX or Central Office Systems, Digital Loop Carrier Systems
• Hotel/Motel Switching Systems
• Direct Inward Dialing (DID) Trunks
• Voice Messaging PBX’s
• High Voltage 2W/4W, 4W/2W Hybrid
