Hey people, i've connected a MITEL 8870 DTMF decoder to port b of my PIC.When i transmit a DTMF the decoder should give 5V on its data vaild
and then the same voltage on it data outputs but i'm only getting 0.75 V on these outputs of the decoder.
When i remove the pic and test the DTMF it works fine giving 5V on DV and data outputs.
Would anyone know why this voltage drop is occuring with the pic in.
The PIC pins are configured to be inputs RB0-3.
