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 of the available line current can be used to power other ele.
• 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 payphone applications
• DTMF - confidence tone input
• Excellent RFI performance
