D82C55AC-2

[aleksa]

I've bought 10 pcs of "82C55" through mail, and received D82C55AC-2.

The problem is that the output high voltage of any pin is not 5V, but
3.8V.

Nothing is connected to the port pins, VCC is 4.85V.

Am I wrong thinking that CMOS chips should have far more than 3.8V on
output pins?

Thanks
