Does anyone here have a SparkFun MicroSD Shield?  Can you tell me what the hex converter IC on it is?  The Eagle files don't give me any information other than to say it's a hex converter.  Is that any run of the mill converter?  Any particular part number?

For reference, this is the product: http://www.sparkfun.com/products/9802

It is M74HC4050, as listed in the properties for that part in the eagle files. To view the properties, right click the part and select properties or select the "i" icon and then click the part.

Danke.  I didn't think of looking a the gate properties.

No problem. I'm usually never looking where I should be either. It's like looking for your eye glasses for 10 minutes, to only realize you are wearing them.

Here's another one, this time on the Ethernet Shield R3.  There's a reset supervisor on it, IC1, which is labeled as 'CAT811TTBI-CT3'.  I'm assuming that's simply an STM811, push-pull, active low IC?  Can anyone verify this please?

And what voltage should it be?  They come in varying voltages: 2.59-2.66V, 2.89-2.96V, 3.04-3.11V, 4.31-4.45V, and 4.56-4.7V.  Since it's ascertaining the 5V line, am I correct that it's a 4.56 - 4.7V one?
