The BA8240F is a kind of 8*8 cross point mixer for telephone.It has line switching and mixing functions for cordless telephone.It solves the problem of cross point switch (unsuitable to mixing) or analog switch (with many control signals).It consists of 64 switches and mixing resistors and 8 mixing amplifiers.Besides,it has a built-in shift resistor and latch to operate serial control of each switch.The typical applications include telephone,answering machine or cordless phone.
There are some features BA8240F as follows.First,8 input signals are selected and mixed by cross point and connected to 8 pins.Secondly,external reset is available by RST pin.Then is serical binary data input.Next is cascade connection by SOUT pin.At last,bias voltage is supplied by VB pin.(IOUT=-1 mA Typ.).
What comes next is about the recommended operating range BA8240F (Ta=25).The VCC (supply voltage) is from 4.5 to 5.5 V.The maximum VIN (input voltage) is 0 dBV.The maximum fCLK (clock frequency) is 100 kHz when duty cycle 50%.The minimum RL (output load resistor) is 10 k at OUT1 to OUT8 pin.
