Hello,

I am trying to find a data sheet for an 8-Pin
Dip in a garage door opener transmitter.  It is from Microchip
and has the following markings :

33912C
SAW
9736

I am pretty sure it is an encoder with a PWM output
similar to the HCS1xx/2xx/3xx family (Although I don't
know if it is a KeeLoq code hopper).

I can find much info on Microchip's web site about garage
door opener circuits and such, but can't find the specific
data sheet for this chip.  Any help would be appreciated.
Thanks,
Jeff
