Description
The L3916 is an electronic component model in the IC Chips product category. It is a device that consists of a speech and dialer circuit. The device provides a DC line interface circuit for terminating the telephone line and an analog amplifier for speech transmission. It supports both DTMF and loop disconnect (pulse) dialing.
Specifications and features
- 2 to 4 wires conversion - Provides the proper DC path for the line current and flexibility to adjust it - Allows parallel phone operation - Provides supply with limited current for external circuitry - Symmetrical high impedance microphone inputs suitable for dynamic electret or piezoelectric transducer - Asymmetrical earphone output suitable for dynamic transducer - Line loss compensation - Internal muting to disable speech during dialing - Lighted dial LED consuming 25% of line current - 32 digits for last number redial buffer - 18 digits for 13 memory redial - Allows mixed mode dialing in either tone or pulse mode - Pacifier tone provides audible indication of valid key pressed in a buzzer and/or in the earphone - Timed PABX pause - Flash initiates timed break: 585ms - Continuous tone for each digit until key release - Uses inexpensive 3.579545MHz ceramic resonator - Powered from telephone line, low operating voltage for long loop application
Application Scenarios
The L3916 electronic component model can be used in various applications such as telecommunication systems, telephone devices, and speech transmission systems.
