The M38510 part of the number refers to Mil Standard 38510. I'm pretty certain that that is the MilStd for TTL ICs. The last part of the number identifies the particular IC. In this case I believe the 01007 is a 5401 (a 7401 with a military temperature range). The BEB may be a 5401 BEB or it may be something else, I'm not sure. Check your usage and see if it conforms to the power, ground, inputs and outputs of a 7401. If it does then I'd say that that's what it is. Joe At 02:09 PM 2/7/03 -0500, you wrote:

Some one gave me something from 70's era aircraft to see if I could repair it. Very simple device 2 Chips & a LED display. Problem is I have no experience looking up the military/government part numbers. Is there any pointer/resources that can help. I don't have the part in front of me but I think it was something like M38510/01007BEB

From what I could tell the M38510 is a government/military PO number?

Thanks, Kev
