mc3372

Hello,i have a question.Can i replace the motorola ic mc3361 with mc3372?Is it pin-to-pin compatible?Thanks

They look p/p compatible with the exception of pin 13 on the 61 is used fr scan control, pin 13 on the 71/72 is used to drive a meter....looking at the internal circuitry, I'd say yes they are interchangeable...


I suggest you have a look here: http://www.discriminator.nl/ic/

The MC3372 is NOT a direct replacement for the MC3361, :mad: internals are different after pin 9. :eek: At least this applies to an existing RC receiver.

If you are intending to build a new receiver using the 3372, it is indeed very similar but will need alternative circuitry to that of the older 3361 from pin 9 onwards. Is it a commercial RX?
