Hi all,

I need help identifying an IC in a device I'm dissecting.  The device is
a the receiver for an "invisible fence" system for pets:  a buried perimeter
wire emits a signal that is picked up by a small receiver attached to the
pet's collar.  The transmitter and receiver are both PIC-based; the receiver
detects the signal with an IC bearing the following logo and part #:

                 ___________________
                /                  /
              /      ____________/
            /______/   _________         9  5  3  3  H
                      /       /
                    /       /
                  /       /            4   0  6  9  U  B
                /_______/



This receiver would work perfectly in a project I'm working on.
Any help on who the manufacturer of the mystery IC would be appreciated.

Thanks,
John Leonard

The 4069 chip is a hex inverter

Bye for now

4069UB=CMOS HEX inverter of series 4000, Unbuffered MAnufactured year 95
Week 33
A very lot of manufacturer make it. For data try Mototrola, Harris,
National etc
Pinning as TTL 7404, Voltage 3-15V typical
One of my favourites.
Often used in analog mode as inverting amplifier: Input voltage via
resistor to inverter input, and another between input and output. Cheap,
simple low-end.
In the named cirquit, replacing the one inverter with two serially
connected inverters instead, makes it an scmitt-trigger. Another use is to
build crystal oscillators. Or RC oscillators, or....

Well... Since we seem to be having fun naming chips...  ;)

Does anyone know what a P85C220 is?  It has a M with a ring around it
(Motorola if I recall correctly).  It would seem to be some kind of
microcontroller.

Thanks!
