What is this chip? (JM38510/10403BEB)

JM38510/10403BEB

It was made in '85, I believe by Fairchild.
It's in a burn-in fixture for a military LED display that I may need
to reproduce. I may found an obsolete chip dealer that might have
some. What I'd like to know is, what is it? I haven't found anything
via Google. Just in case I can't get this IC I'm hoping there's an
equivalent commercial device still available.

Thanks,

According to my parts database, it is a Fairchild DM54153 a Dual
1-of-4 Line Data Selector/Multiplexer I might have a couple in stock,
somewhere.

Hmmm... I found inconclusive references to a 9615 dual differential
line receiver. But I'm expecting something with more like a dozen
outputs as this chip drives a dozen displays (it's driven by a 556).
Wish I had a schematic.

I accidentally replied to your E-mail address, so I will post it
here:


National Semiconductor had it listed as a DM54153, a Dual 1-of-4 Line
Data
Selector/Multiplexer when they were shifting things to Fairchild.

TI says it is a SN55114, a Dual Differential Line Driver. One or
both of them are/were wrong.

After National Semiconductor transferred their logic products line to
Fairchild, it isn't on the National or the Fairchild websites.

www.chipdocs.com claims to have a data sheet, if you want to pay 95
dollars to register. I don't know if Partminer has any data, I no longer
have
an account.

According to Mil Ref Guide , 10403 = 55114 , 38510/01403 = 54153
You transposed the numbers wrong. Logon to TI and order the Military
Designers Reference Guide.

This helps make some progress...

The TI site shows the SN55114 as a JM38510/10403BEA.
A 1978 Fairchild catalog lists all of the 10403xxx's as versions of
the 9614 dual line driver (different packages & lead finishes.)

Just found a NASA site that shows 55114 and 9614 as being generic
numbers for MIL-M-38510/10403, line receiver, dual differential, and
again the 55114 as being generic for MIL-M-38510/10403, line driver,
dual differential. I don't understand how it can be both.
A TI data book shows the SN55114 as a driver.
So confusing!

Well, typos do happen, it isn't going to be both a receiver and a
transmitter.
The definitive source is :
http://www.dscc.dla.mil/Programs/Smcr/

If you type in "10403", it will tell you TI is still a valid source for the
part, and it is a line driver.
