29301 - what's this part?

[max-man]

What on earth is this part:

23901

Looks like a decoder to me but with inputs on pins 1, 2, 14, 15 and
outputs on 3, 4, 5, 6, 7, 9, 10, 11, 12, 13

Can it be subbed with any other chip?


Thanks

It's old TTL, originally the Fairchild 9301, also the National DM9301
or the Signetics S8252. (Warning, I think Intel used 8252 for
something different).

There doesn't seem to be a direct replacment in the SN74xx series.

A lot of the old 93xx and other 9xxx TTL now go by the 74xx numbers
that TI gave them. Example: the 9316 is now the 74161. The few
that they didn't renumber/redesign used SN293xx numbers.

Thanks for the information Mark.
