I believe the kit list may have a typo and it should really be the 4840 which is a 5 volt device, hence the ease in getting it from Newark (lead time on the 34840 was 47 days BTW) I will check into this and hopefully Kevin Watson will see the post and let all of know for sure.

Sorry, just got back from a quick trip to the other coast.
Go ahead and get the TSOP4840 device. All of the development was done with this device and I know it works. Actually, I suspect that they're the same device. When they go to screening, the parts that pass at 3.3 volts probably just get dumped in the TSOP34840 bin.
