Description  
The telephone circuit U4089B-P is a linear integrated circuit for use in feature phones,  
answering machines and fax machines. It contains the speech circuit, sidetone  
equivalent and ear protection rectifiers. The circuit is line-powered and contains all  
components necessary for the amplification of signals and adaptation to the line.  
An integrated voice switch with loudspeaker amplifier enables loudhearing or hands-  
free operation. With an anti-feedback function, acoustical feedback during loud-  
hearing can be reduced significantly. The generated supply voltage is suitable for a  
wide range of peripheral circuits.  
Electrostatic sensitive device.  
Observe precautions for handling.
