PBL3853 Universal Speech Circuit

The PBL 3853 is a biopolar integrated speech circuit with specific parameters making it highly suitable to be used as a line interface and speech circuit in a telephone line powered electronic payphone. Emphasis has been put on low current consumption in the IC thus facilitating that a greater part .

PBL3853 Features

* Low own current consumption

* Can operate both with active and passive impedance towards the line

* Derives a high current from the line for auxiliary functions, 12 mA at 16 mA line current

* Separate mute inputs for transmitter and receiver (receiver cut off)
