Product details

Description

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.

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).
Line length regulation possible (line loss compensation.
Comes in 18 pin DIP and 20-pin SO package.
High line current operation, max. 130 mA.
Especially suitable for pa.
