BU8241F General Description


The BU8241F, BU8241FS, BU8242F, and BU8244F are ICs developed for use with cordless telephones, and are equipped with switching and mixing functions. In addition, these ICs are provided with an internal power save function which enables the circuit to be run on line current if the power supply fails, by connecting a switch between the circuit and a new handset, reducing line current consumption. A series of these ICs is also under development, based on the number of circuits.

BU8241F Features

1) Eight input signals are selected and mixed by a cross-point, and output to eight pins (BU8241F/BU8241FS).
2) A power save mode enables the circuit to run on line current if the power supply fails.
    1. Line current consumption reduced (IDD2 = 580A)
    2. IN1  OUT1 and IN2  OUT2 only are on
3) Serial binary data input.
4) Low voltage and current consumption.

BU8241F Typical Application

Telephones, telephone answering machines, cordless telephones
