Cross point mixer for telephones
BU8241F / BU8241FS / BU8242F / BU8244F
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.
Applications
Telephones, telephone answering machines, cordless
telephones
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

3) Serial binary data input.
4) Low voltage and current consumption.
