Overview
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.
