Communication ICs

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.

FApplications

Telephones, telephone answering machines, cordless

telephones

FFeatures

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

(I

DD2

= 580µA)

2. IN1

!

OUT1 and IN2

!

OUT2 only are on

3) Serial binary data input.

4) Low voltage and current consumption.
