s DESCRIPTION
The FUJITSU MB86434 is an AIU (audio interface unit) LSI for +5 V single-power source digital telephone devices,
manufactured using CMOS process technology. The codec transmission filter characteristics meet G.712 standards,
and can handle input and output in A-Law, µ-Law and linear conversion modes. The MB86434 also contains the
necessary DTMF, microphone and receiver amps for telephone devices.
s FEATURES
